                                  THE COMPANY
 
    The Company is one of the largest operators of cable television systems in
the United States, with approximately 2,889,000 subscribers in 19 states as of
June 30, 1997, based on the number of basic subscribers in systems which are
currently majority owned and managed by the Company (after giving effect to the
closing of the A-R Cable Transaction, as described in the Company's Form 10-Q
for the quarter ended June 30, 1997). The Company also has ownership interests
in companies that produce and distribute national and regional programming
services and provide advertising sales services for the cable television

CABLE TELEVISION
 
    The cable television systems that are currently majority owned and managed
by the Company (the "Company's cable television systems") served approximately
2,889,000 subscribers in 19 states as of June 30, 1997 (after giving effect to
the closing of the A-R Cable Transaction, as described in the Company's Form
10-Q for the quarter ended June 30, 1997). The Company's cable television
systems have generally been characterized by relatively high revenues per
subscriber ($38.19 for June 1997) and a high ratio of premium service units to
basic subscribers (1.4:1 for June 1997). In calculating revenue per subscriber,
the Company includes only recurring service revenues and excludes installation
charges and certain other revenues such as advertising, pay-per-view and home
shopping revenues.

subsidiaries (the "Restricted Group") served approximately 1,937,000 subscribers
as of June 30, 1997, primarily in and around metropolitan New York City
(including in the boroughs of Brooklyn and The Bronx, on Long Island, in
Fairfield County, Connecticut, in New Jersey and in Westchester County, New
York) and in and around Boston, Massachusetts. The revenue per subscriber and
ratio of premium service units to basic subscribers for cable television systems
in the Restricted Group for June 1997 were $41.51 and 1.6:1, respectively.
 
    The cable television operations currently in the Company's Unrestricted
Group ("Unrestricted Cable") served approximately 952,000 subscribers as of June
30, 1997 in Ohio and 15 other states. The revenue per subscriber and ratio of

                                  RISK FACTORS
 
    Purchase of the Debt Securities offered hereby involves various risks,
including the following principal factors, which, together with the other
matters set forth herein, in any Prospectus Supplement or incorporated by
reference herein, should be carefully considered by prospective investors.
 
    SUBSTANTIAL INDEBTEDNESS AND HIGH DEGREE OF LEVERAGE.  The Company has
incurred substantial indebtedness and issued substantial amounts of mandatorily
redeemable preferred stock, primarily to finance acquisitions and expansion of
its operations, to refinance outstanding indebtedness and, to a lesser extent,
for investments in and advances to affiliates. The Company's consolidated debt
plus the Company's 11 3/4% Series H Redeemable Exchangeable Preferred Stock and
11 1/8% Series M Redeemable Exchangeable Preferred Stock aggregated
approximately $5.6 billion at June 30, 1997. See Note 4 of Notes to the
Consolidated Financial Statements. As a result of the Company's high level of
indebtedness and the significant amount of redeemable preferred stock, the
Company has significant cash requirements to service indebtedness and to pay
dividends and redemption amounts on redeemable preferred stock, increasing the
Company's vulnerability to adverse developments in its business and adverse
economic and industry conditions.
 
    NET LOSSES AND STOCKHOLDERS' DEFICIENCY.  The Company reported net losses
applicable to common stockholders for the six months ended June 30, 1997 and
1996 of $240.7 million and $218.6 million, respectively, and for the years ended
December 31, 1996, 1995 and 1994 of $459.9 million, $337.7 million and $321.5
million, respectively. At June 30, 1997, the Company had a stockholders'
deficiency of $2.6 billion. The net losses primarily reflect high levels of
interest expense and depreciation and amortization charges relating to the
depreciation of assets obtained through, and debt incurred to finance,
acquisitions. Interest expense and depreciation and amortization charges
remained at a high level throughout 1994, 1995 and 1996 and will continue at
high levels throughout 1997 and future years as a result of previously
completed, pending and future acquisitions, expected capital expenditures and
additional investments in the Company's programming operations. The Company
expects to continue incurring substantial losses for at least the next several
years. See "Management's Discussion and Analysis--Liquidity and Capital
Resources".
 
    POSSIBLE NONCOMPLETION OF CERTAIN TRANSACTIONS.  There can be no assurances
that the Company's pending transactions referred to in the Company's Form 8-Ks
filed June 10, 1997, July 10, 1997 and September 9, 1997 and in the Company's
Form 10-Q for the fiscal quarter ended June 30, 1997 will be consummated in a
timely manner or at all.
 
    POSSIBLE SEPARATION OF RAINBOW MEDIA FROM THE COMPANY.  If the pending
transactions with Tele-Communications, Inc. ("TCI") described in the Company's
Form 8-K dated June 10, 1997 are consummated, Cablevision, the issuer of the
Debt Securities, will be a wholly-owned subsidiary of CSC Parent Corporation
("CSC Parent"), the indirect subsidiaries of TCI contributed in such
transactions (the "TCI Contributed Entities") will be held as separate direct
subsidiaries of CSC Parent and Rainbow Media will continue to be a 75%-owned
subsidiary of Cablevision (with NBC owning the remaining 25% interest). The
Contribution and Merger Agreement with TCI permits the Company under certain
circumstances to restructure these holdings so that Rainbow Media becomes a
separate subsidiary of CSC Parent (and would no longer be a subsidiary of
Cablevision) and the TCI Contributed Entities become subsidiaries of
Cablevision. Following such transactions, the residual equity value of Rainbow
Media would no longer support the ability to pay interest and principal on the
Debt Securities and other debt.
 
    NEED FOR ADDITIONAL FINANCING.  The Company's business requires substantial
investment on a continuing basis to finance capital expenditures and related
expenses for, among other things, upgrade of the Company's cable plant, the
offering of new services and the further participation in existing services, the
funding of costs of cable programming services prior to their becoming cash-flow
positive, and the servicing, repayment or refinancing of its indebtedness and
mandatorily redeemable preferred stock. The
 
                                       5
<PAGE>
   
Company will require significant additional financing, through debt and/or
equity issuances, to meet its capital expenditure plans and to pay the principal
of and interest on its debt and to pay dividends and make redemption payments on
its preferred stock. The Company also intends to incur additional costs to
facilitate the startup of such adjunct businesses as high speed data service,
digital video service and residential telephony. Depending upon the timing and
scope of the rollout of these businesses, the Company may require additional
capital. Depending on the scope of the Company's participation in the PCS and
DBS ventures, additional capital may also be required for these businesses. In
addition, the Company may require additional capital if it elects to pay cash to
(i) acquire ITT Corporation's remaining interest in MSG following an exercise by
ITT Corporation of its put rights or by the Company of its call rights or (ii)
make the Cablevision of NYC Payment (as defined herein) to Charles F. Dolan due
under the Cablevision of NYC Agreement (as defined herein). There can be no
assurance that the Company will be able to issue additional debt or obtain
additional equity capital on satisfactory terms, or at all, to meet its future
financing needs. See "Management's Discussion and Analysis--Liquidity and
Capital Resources".
    
 
    FUTURE CAPITAL EXPENDITURES AND COMMITMENTS.  The Company intends to make
substantial capital expenditures, including major system upgrades, with respect
to its cable television systems over the next several years. In addition, the
Company, through Rainbow Media and its subsidiaries, has entered into numerous
contracts relating to cable television programming, including rights agreements
with professional and other sports teams. These contracts typically require
substantial payments over extended periods of time. See Note 11 of Notes to the
Consolidated Financial Statements for a discussion of commitments.
 
   
    The Company has a commitment to fund annual payments to Charles F. Dolan

"Business--Programming Operations" in the Form 10-K and "Management's Discussion
and Analysis--Liquidity and Capital Resources".
    
 
    INTANGIBLE ASSETS.  The Company had total assets at June 30, 1997 of $4.6
billion, of which $2.4 billion were intangible assets, consisting of franchises,
affiliation agreements, excess cost over fair value of net assets acquired and
deferred financing, acquisition and other costs. It is possible that no cash
would be recoverable from the voluntary or involuntary sale of these intangible
assets.
 
    VOTING CONTROL BY MAJORITY STOCKHOLDERS; DISPARATE VOTING RIGHTS.  As of
June 30, 1997, Charles F. Dolan beneficially owned and possessed sole voting
power with respect to 10,805 shares or 0.1% of the Company's outstanding Class A
common stock (the "Class A Common Stock") and 4,859,281 shares or 43.7% of the
Company's outstanding Class B common stock (the "Class B Common Stock" and,
collectively with the Class A Common Stock, the "Common Stock"). In addition, as
of June 30, 1997, an aggregate of 1,240,000 shares or 11.2% of the outstanding
Class B Common Stock were held by a Grantor Retained Annuity Trust (the "GRA
Trust") established by Mr. Dolan for estate planning purposes. Mr. Dolan may be
deemed to have beneficial ownership of the shares of Class B Common Stock held
by the GRA Trust due to his right to reacquire the Class B Common Stock held by
the GRA Trust by substituting other property of equivalent value, but, until
such event, the GRA Trust, through its co-trustees (who are Mr. Dolan and his
spouse) has the power to vote and dispose of the shares of Class B Common Stock
held by it. As a result of his beneficial ownership of the shares held by the
GRA Trust, as of June 30, 1997, Mr. Dolan beneficially owned 10,805 shares or
0.1% of the Company's outstanding Class A Common Stock and 6,099,281 shares or
54.9% of the Company's outstanding Class B Common Stock. On a combined basis,
these shares represented 24.6% of the total number of shares of both classes of
Common Stock and 48.8% of the total voting power of the Common Stock. Other
trusts established by Mr. Dolan for the benefit of certain Dolan family members,
and as to which Mr. Dolan disclaims beneficial ownership, owned, as of June 30,
1997, an additional 40,000 shares of Class A Common Stock or 0.3% of the Class A
Common Stock and 5,019,928 shares of the Class B Common Stock or 45.1% of the
Class B Common Stock and 40.2% of the total voting power of all classes of the
Common Stock. As a result of this
 
                                       6
<PAGE>
stock ownership, Dolan family members have the power to elect all the directors
subject to election by holders of the Class B Common Stock, which directors
constitute 75% of the entire Board of Directors of the Company. Moreover,
because holders of Class B Common Stock are entitled to ten votes per share
while holders of Class A Common Stock are entitled to one vote per share, Dolan
family members may control stockholder decisions on matters in which holders of
Class A and Class B Common Stock vote together as a class. These matters include
the amendment of certain provisions of the Company's certificate of
incorporation (the "Certificate of Incorporation") and the approval of
fundamental corporate transactions, including mergers. In addition, because the
affirmative vote or consent of the holders of at least 66 2/3% of the
outstanding shares of the Class B Common Stock, voting separately as a class, is
required to approve (i) the authorization or issuance of any additional shares
of Class B Common Stock and (ii) any amendment, alteration or repeal of any of
the provisions of the Certificate of Incorporation which adversely affects the
powers, preferences or rights of the Class B Common Stock, Dolan family members
also have the power to prevent such issuance or amendment. The voting rights of
the Class B Common Stock beneficially owned by the Dolan family members will not
be modified as a result of any transfer of legal or beneficial ownership
thereof. If the pending transactions with TCI are consummated, the Common Stock
of the Dolan family members will be converted into shares of common stock of CSC
Parent and the Dolan family members will continue to maintain the voting rights
set forth above, including the voting rights resulting from the ownership of a
majority of the total voting power of CSC Parent's common stock.
 
    RESTRICTIVE COVENANTS.  The Company's principal bank credit facility (the
"Credit Agreement") and certain of the Company's other debt instruments contain
various financial and operating covenants which, among other things, require the
maintenance of certain financial ratios and restrict the Company's ability to
borrow funds from other sources and to utilize funds for various purposes,
including investments in certain subsidiaries. Violation of the covenants in the
Credit Agreement or in the indentures governing the Company's publicly-issued
debentures and notes could result in a default under the Credit Agreement which
would permit the bank lenders thereunder (i) to restrict the Company's ability
to borrow undrawn funds under the Credit Agreement and (ii) to accelerate the
maturity of borrowings thereunder. See "Management's Discussion and
Analysis--Liquidity and Capital Resources".
 
    RISKS RELATED TO REGULATION.  The Company's cable television operations may
be adversely affected by government regulation, the impact of competitive forces
and technological changes. In 1992, Congress enacted the 1992 Cable Act, which
represented a significant change in the regulatory framework under which cable
television systems operate. In 1993 and 1994, the Federal Communications
Commission ("FCC") ordered reductions in cable television rates. In 1995, a
Federal appeals court upheld the material aspects of the FCC's rate regulation
scheme. Congress subsequently enacted legislation (the "Telecommunications Act
of 1996") that relaxes the regulation of cable television rates; however, the
most significant rate regulation relaxation affecting the Company will not occur
until after March 31, 1999. See "Business-- Cable Television
Operations--Competition" and "Business--Cable Television Operations--Regulation"
in the Form 10-K.
 
    RISK OF COMPETITION.  Cable operators compete with a variety of distribution
systems, including broadcast television stations, DBS, multichannel multipoint
distribution services ("MMDS"), satellite master antenna systems ("SMATV") and
private home dish earth stations. For example, four DBS systems are now
operational in the United States, some with investment by companies with
substantial resources such as Hughes Electronics Corp., AT&T Corp. and News
Corporation. The 1992 Cable Act prohibits a cable programmer that is owned by or
affiliated with a cable operator (such as Rainbow Media) from unreasonably
discriminating among or between cable operators and other multichannel video
distribution systems with respect to the price, terms and conditions of sale or
distribution of the programmer's service and from unreasonably refusing to sell
service to any multichannel video programming distributor. Cable systems also
compete with the entities that make videotaped movies and programs available for
home rental. The 1992 Cable Act regulates the ownership by cable operators of
MMDS and SMATV. Under the
 
                                       7
<PAGE>
Telecommunications Act of 1996, the cross-ownership provisions do not apply to
any cable operator in a franchise area in which a cable operator faces
competition from video programming distributors meeting certain statutory
requirements. The Telecommunications Act of 1996 gives telephone companies and
other video providers the option of providing video programming to subscribers
through "open video systems" ("OVS"), a wired video delivery system similar to a
cable television system that would not require a local cable franchise. Several
OVS operators have sought to enter New York City, Boston and Westchester County,
New York. Additional video competition to cable systems is possible from new
wireless local multipoint distribution services ("LMDS") authorized by the FCC,
for which spectrum will be auctioned by the FCC in late 1997.
 
    COMPETITION FROM TELEPHONE COMPANIES.  The 1984 Cable Act barred
co-ownership of telephone companies and cable television systems operating in
the same service areas. The Telecommunications Act of 1996 repeals this
restriction and permits a telephone company to provide video programming
directly to subscribers in its telephone service territory, subject to certain
regulatory requirements, but generally prohibits a telephone company from
acquiring an in-region cable operator, except in certain small markets under
certain circumstances. Telephone companies (Ameritech Corp. in Ohio and Southern
New England Telephone Co. in Connecticut) have obtained or applied for local
franchises to construct and operate cable television systems in several
communities in which the Company currently holds cable franchises, and in
certain locations have commenced offering service. Neither the 1984 Cable Act
nor the 1992 Cable Act bars a telephone company from acquiring cable systems
outside its telephone service area. Several Regional Bell operating companies
have purchased or made investments in such cable systems. See "Business--Cable
Television Operations--Regulation" in the Form 10-K.
 
    RISK OF NON-EXCLUSIVE FRANCHISES AND FRANCHISE RENEWALS.  The Company's
cable television systems are operated primarily under non-exclusive franchise
agreements with local government franchising authorities, in some cases with the
approval of state cable television authorities. The Company's business is
dependent on its ability to obtain and renew its franchises. Although the
Company has never lost a franchise as a result of a failure to obtain a renewal,
its franchises are subject to non-renewal or termination under certain
circumstances. In certain cases, franchises have not been renewed at expiration
and the Company operates under either temporary operating agreements or without
a license while negotiating renewal terms with the franchising authorities. See
"Business--Cable Television Operations-- Franchises" in the Form 10-K.

                                USE OF PROCEEDS
 
    Except as may otherwise be set forth in the applicable Prospectus
Supplement, the net proceeds from the sale of the Debt Securities will be added
to the Company's general funds and used for general corporate purposes,
including the repayment of indebtedness.
 
            DEFICIENCY OF EARNINGS AVAILABLE TO COVER FIXED CHARGES
 
    As set forth below, the Company has a deficiency of earnings available to
cover fixed charges for each of 1996, 1995, 1994, 1993 and 1992 and for the six
months ended June 30, 1997 on an historical basis.

                         DESCRIPTION OF DEBT SECURITIES
 
    The Debt Securities may be issued from time to time in one or more series.
The particular terms of each series of Debt Securities offered by any Prospectus
Supplement or Prospectus Supplements will be described therein. The Senior Debt
Securities will be issued under an Indenture (the "Senior Indenture"), between
the Company and The Bank of New York (the "Senior Trustee") prior to the
issuance of the Senior Debt Securities. The Subordinated Debt Securities will be
issued under an Indenture (the "Subordinated Indenture"), between the Company
and The Bank of New York (the "Subordinated Trustee") prior to the issuance of
the Subordinated Debt Securities. The Senior Indenture and the Subordinated
Indenture are referred to herein individually as an "Indenture" and collectively
as the "Indentures", and the Senior Trustee and the Subordinated Trustee are
referred to herein individually as a "Trustee" and collectively as the
"Trustees". A copy of each Indenture is filed as an exhibit to the Registration
Statement of which this Prospectus forms a part. The Indentures are subject to
and are governed by the Trust Indenture Act of 1939, as amended.
 
    The Debt Securities offered pursuant to this Prospectus will be limited to
$1,000,000,000 aggregate principal amount (or (i) its equivalent (based on the
applicable exchange rate at the time of sale), if Debt Securities are issued
with principal amounts denominated in one or more foreign currencies or currency
units as shall be designated by the Company, or (ii) such greater amount, if
Debt Securities are issued at an original issue discount, as shall result in
aggregate proceeds of $1,000,000,000 to the Company). The statements herein
relating to the Debt Securities and the Indentures are summaries and are subject
to the detailed provisions of the Indentures. Where no distinction is made
between the Senior Debt Securities and the Subordinated Debt Securities or
between the Senior Indenture and the Subordinated Indenture, such summaries
refer to any Debt Securities and either Indenture. The following summaries of
certain provisions of the Indentures do not purport to be complete, and where
reference is made to particular provisions of the Indentures, such provisions,
including the definitions of certain terms, are incorporated by reference as a
part of such summaries or terms, which are qualified in their entirety by such
reference. The definitions of certain capitalized terms used in the following
summary are set forth below under "Certain Definitions".
 
GENERAL
 
    The Debt Securities may be secured or general unsecured obligations of the
Company. The Indentures do not limit the aggregate amount of Debt Securities
which may be issued thereunder, and Debt Securities may be issued thereunder
from time to time in separate series up to the aggregate amount from time to
time authorized by the Company for each series. Unless otherwise specified in
the Prospectus Supplement, the Senior Debt Securities when issued will be
unsubordinated obligations of the Company and will rank equally and ratably with
all other unsubordinated indebtedness of the Company. The Subordinated Debt
Securities when issued will be subordinated in right of payment to the prior
payment in full of all Senior Indebtedness (as defined) of the Company as
described under "Subordination of Subordinated Debt Securities" and in the
Prospectus Supplement applicable to an offering of Subordinated Debt Securities.
 
   
    The applicable Prospectus Supplement or Prospectus Supplements will describe
the following terms of the series of Debt Securities in respect of which this
Prospectus is being delivered: (1) the title and ranking of such Debt Securities
and whether they will be Senior Debt Securities or Subordinated Debt Securities;
(2) any limit on the aggregate principal amount of such Debt Securities; (3) the
person to whom any interest on any Debt Security of the series shall be payable

on such Debt Securities will be payable and the regular record date for any
interest payable on any interest payment date; (6) the place or places where the
principal of, premium, if
    
 
                                       10
<PAGE>
any, and interest on such Debt Securities will be payable; (7) the period or
periods within which, the events upon the occurrence of which, and the price or
prices at which, such Debt Securities may, pursuant to any optional or mandatory
provisions, be redeemed or purchased, in whole or in part, by the Company and
any terms and conditions relevant thereto; (8) the obligations of the Company,
if any, to redeem or repurchase such Debt Securities at the option of the
Holders; (9) the denominations in which any such Debt Securities will be
issuable, if other than denominations of $1,000 and any integral multiple
thereof; (10) any index or formula used to determine the amount of payments of
principal of and any premium and interest on such Debt Securities; (11) the
currency, currencies or currency unit or units of payment of principal of and
any premium and interest on such Debt Securities if other than U.S. dollars;
(12) if the principal of, or premium, if any, or interest on such Debt

such election is to be made; (13) if other than the principal amount thereof,
the portion of the principal amount of such Debt Securities of the series which
will be payable upon acceleration of the maturity thereof; (14) if the principal
amount of any Debt Securities which will be payable at the maturity thereof will
not be determinable as of any date prior to such maturity, the amount which will
be deemed to be the outstanding principal amount of such Debt Securities; (15)
the applicability of any provisions described under "Defeasance"; (16) whether
any of such Debt Securities are to be issuable in permanent global form ("Global
Security") and, if so, the terms and conditions, if any, upon which interests in
such Securities in global form may be exchanged, in whole or in part, for the
individual Debt Securities represented thereby; (17) the applicability of any
provisions described under "Event of Default" and any additional Event of
Default applicable thereto; (18) any deletions from, modifications of or
additions to the covenants applicable to such Debt Securities; (19) whether such

applicable to any such original issue discount Debt Securities will be described
in the applicable Prospectus Supplement.
 
    If the purchase price of any of the Debt Securities is denominated in a
foreign currency or currencies or a foreign currency unit or units or if the

payable in a foreign currency or currencies or a foreign currency unit or units,
the restrictions, elections, general tax considerations, specific terms and
other information with respect to such issue of Debt Securities will be set
forth in the applicable Prospectus Supplement.
 
    Since the Company is primarily a holding company, the rights of the Company,
and hence the right of creditors of the Company (including the Holders of Debt
Securities), to participate in any distribution of the assets of any subsidiary
upon its liquidation or reorganization or otherwise is necessarily subject to
the prior claims of creditors of any such subsidiary, including trade creditors,
except to the extent that claims of the Company itself as a creditor of the
subsidiary may be recognized.
 
    The Indentures do not contain any provisions that limit the ability of the
Company to incur indebtedness or that afford Holders of the Debt Securities
protection in the event of a highly leveraged or similar transaction involving
the Company, other than as described below under "Certain Covenants of the
Company--Covenants Applicable to All Debt Securities--Limitation on
Indebtedness".
 
FORM, EXCHANGE, REGISTRATION, CONVERSION, TRANSFER AND PAYMENT
 
    Unless otherwise indicated in the applicable Prospectus Supplement, the Debt
Securities will be issued only in fully registered form in denominations of
$1,000 or integral multiples thereof. Unless otherwise indicated in the
applicable Prospectus Supplement, payment of principal, premium, if any, and
 
                                       11
<PAGE>
interest on the Debt Securities will be payable, and the exchange, conversion
and transfer of Debt Securities will be registerable, at the office or agency of
the Company maintained for such purposes and at any other office or agency
maintained for such purpose. No service charge will be made for any registration
of transfer or exchange of the Debt Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
imposed in connection therewith.
 
    All monies paid by the Company to a Paying Agent for the payment of
principal of and any premium or interest on any Debt Security which remain
unclaimed for two years after such principal, premium or interest has become due
and payable may be repaid to the Company and thereafter the Holder of such Debt
Security may look only to the Company for payment thereof.
 
BOOK-ENTRY DEBT SECURITIES
 
    The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Securities that will be deposited with, or on behalf
of, a Depositary ("Depositary") or its nominee identified in the applicable
Prospectus Supplement. In such a case, one or more Global Securities will be
issued in a denomination or aggregate denomination equal to the portion of the
aggregate principal amount of Outstanding Debt Securities of the series to be
represented by such Global Security or Securities. Unless and until it is
exchanged in whole or in part for Debt Securities in registered form, a Global
Security may not be registered for transfer or exchange except as a whole by the
Depositary for such Global Security to a nominee of such Depositary or by a
nominee of such Depositary to such Depositary or another nominee of such
Depositary or by such Depositary or any nominee to a successor Depositary or a
nominee of such successor Depositary and except in the circumstances described
in the applicable Prospectus Supplement.
 
    The specific terms of the depositary arrangement with respect to any portion
of a series of Debt Securities to be represented by a Global Security will be
described in the applicable Prospectus Supplement. The Company expects that the
following provisions will apply to depositary arrangements.
 
    Unless otherwise specified in the applicable Prospectus Supplement, Debt
Securities which are to be represented by a Global Security to be deposited with
or on behalf of a Depositary will be represented by a Global Security registered
in the name of such Depositary or its nominee. Upon the issuance of such Global
Security, and the deposit of such Global Security with or on behalf of the
Depositary for such Global Security, the Depositary will credit, on its
book-entry registration and transfer system, the respective principal amounts of
the Debt Securities represented by such Global Security to the accounts of
institutions that have accounts with such Depositary or its nominee
("participants"). The accounts to be credited will be designated by the
underwriters or agents of such Debt Securities or by the Company, if such Debt
Securities are offered and sold directly by the Company. Ownership of beneficial
interest in such Global Security will be limited to participants or Persons that
may hold interests through participants. Ownership of beneficial interests by
participants in such Global Security will be shown on, and the transfer of that
ownership interest will be effected only through, records maintained by the
Depositary or its nominee for such Global Security. Ownership of beneficial
interests in such Global Security by Persons that hold through participants will
be shown on, and the transfer of such ownership interests within such
participant will be effected only through, records maintained by such
participant. The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in certificated form. The
foregoing limitations and such laws may impair the ability to transfer
beneficial interests in such Global Securities.
 
    Debt Securities will be issued in fully registered, certificated form
("Definitive Securities") to holders or their nominees, rather than to the
Depositary or its nominee, only if (i) the Depositary advises the applicable
Trustee in writing that the Depositary is no longer willing or able to discharge
properly its responsibilities as depository with respect to such Debt Securities
and it is unable to locate a qualified successor, (ii) the Company, at its
option, elects to terminate the book-entry system or (iii) after the
 
                                       12
<PAGE>
occurrence of an Event of Default with respect to such Debt Securities, a holder
of Debt Securities advises the applicable Trustee in writing that it wishes to
receive a Definitive Security.
 
    Upon the occurrence of any event described in the immediately preceding
paragraph, the applicable Trustee will be required to notify all applicable
holders through the Depositary and its Participants of the availability of
Definitive Securities. Upon surrender by the Depositary of the definitive
certificates representing the corresponding Debt Securities and receipt of
instructions for re-registration, the applicable Trustee will reissue such Debt
Securities as Definitive Securities to such holders.
 
   
    So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Securities
represented by such Global Security for all purposes under the applicable
Indenture. Unless otherwise specified in the applicable Prospectus Supplement,
owners of beneficial interests in such Global Security will not be entitled to
have Debt Securities of the series represented by such Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of Debt Securities of such series in certificated form and will not be
considered the holders thereof for any purposes under the applicable Indenture.
Accordingly, each Person owning a beneficial interest in such Global Security
must rely on the procedures of the Depositary and, if such Person is not a
participant, on the procedures of the participant through which such Person owns
its interest, to exercise any rights of a Holder under the applicable Indenture.
The Company understands that under existing industry practices, if the Company
requests any action of Holders or an owner of a beneficial interest in such
Global Security desires to give any notice or take any action a Holder is
entitled to give or take under the applicable Indenture, the Depositary would
authorize the participants to give such notice or take such action, and
participants would authorize beneficial owners owning through such participants
to give such notice or take such action or would otherwise act upon the
instructions of beneficial owners owning through them.
    
 
    Principal of and any premium and interest on a Global Security will be
payable in the manner described in the applicable Prospectus Supplement.

the applicable Prospectus Supplement, the following covenants contained in the
Indentures shall be applicable with respect to any series of Debt Securities:
 
    LIMITATION ON INDEBTEDNESS.  The Indentures provide that the Company shall
not, and shall not permit any Restricted Subsidiary to, directly or indirectly
incur, create, issue, assume, guarantee or otherwise become liable for,
contingently or otherwise, or become responsible for the payment of,
contingently or otherwise, any Indebtedness (other than Indebtedness between or
among any of the Company and Restricted Subsidiaries) unless, after giving
effect thereto, the Cash Flow Ratio shall be less than or equal to 9 to 1.
 
   
    LIMITATION ON RESTRICTED PAYMENTS.  The Indentures provide that, so long as
any of the Debt Securities of such series remain outstanding, the Company shall
not, and shall not permit any Restricted Subsidiary to, make any Restricted
Payment if (a) at the time of such proposed Restricted Payment, a Default or
Event of Default shall have occurred and be continuing or shall occur as a
consequence of such Restricted Payment or (b) immediately after giving effect to
such Restricted Payment, the aggregate of all Restricted Payments that shall
have been made on or after July 1, 1988 would exceed the sum of:
    
 
        (i) $25,000,000, plus
 
   
        (ii) an amount equal to the difference between (A) the Cumulative Cash
    Flow Credit and (B) 1.2 multiplied by Cumulative Interest Expense.
    
 
    For purposes of the "Limitation on Restricted Payments" covenant, the amount
of any Restricted Payment, if other than cash, shall be based upon fair market
value as determined by the Board of Directors of the Company, whose good faith
determination shall be conclusive.
 
   
    The foregoing provisions do not prevent: (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at such date of
declaration such payment complied with the above provisions; (ii) the
retirement, redemption, purchase, defeasance or other acquisition of any shares
of the Company's capital stock or warrants, rights or options to acquire capital
stock of the Company, in exchange for, or out of the proceeds of a sale (within
one year before or 180 days after such retirement, redemption, purchase,
defeasance or other acquisition) of, other shares of the Company's capital stock
or warrants, rights or options to acquire capital stock of the Company; and
(iii) the redemption of, or payments of cash dividends on, the Company's 8%
Series C Cumulative Preferred Stock (the "Series C Preferred Stock") outstanding
on January 1, 1997, which redemption or dividends are provided for by the terms
of the Series C Preferred Stock in effect on such date (or the redemption of or
payment of cash dividends on any security of the Company issued in exchange for
or upon the conversion of such Series C Preferred Stock; PROVIDED that the
aggregate amount payable pursuant to the terms of such security is no greater
than the aggregate amount payable pursuant to the terms of the Series C
Preferred Stock). For purposes of determining the aggregate permissible amount
of Restricted Payments in accordance with clause (b) of the first paragraph of
this covenant, all amounts expended pursuant to clauses (i) and (iii) of this
paragraph shall be included and all amounts expended or received pursuant to
clause (ii) of this paragraph shall be excluded; PROVIDED, HOWEVER, that amounts
paid pursuant to clause (i) of this paragraph shall be included only to the
extent that such amounts were not previously included in calculating Restricted
Payments.
    
 
    For the purposes of the foregoing provisions, the net proceeds from the
issuance of shares of capital stock of the Company upon conversion of
Indebtedness shall be deemed to be an amount equal to (i) the
 
                                       20
<PAGE>
accreted value of such Indebtedness on the date of such conversion and (ii) the
additional consideration, if any, received by the Company upon such conversion
thereof, less any cash payment on account of fractional shares (such
consideration, if in property other than cash, to be determined by the Board of
Directors of the Company, whose good faith determination shall be conclusive).
If the Company makes a Restricted Payment which, at the time of the making of
such Restricted Payment, would in the good faith determination of the Company be
permitted under the requirements of this covenant, such Restricted Payment shall
be deemed to have been made in compliance with this covenant notwithstanding any
subsequent adjustments made in good faith to the Company's financial statements
affecting Cumulative Cash Flow Credit or Cumulative Interest Expense for any
period.
 
   
    LIMITATION ON INVESTMENTS IN UNRESTRICTED SUBSIDIARIES AND AFFILIATES.  The
Indentures provide that the Company shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, (i) make any Investment or
(ii) allow any Restricted Subsidiary to become an Unrestricted Subsidiary (a
"redesignation of a Restricted Subsidiary"), in each case unless (a) no Default
or Event of Default shall have occurred and be continuing or shall occur as a
consequence of such Investment or such redesignation of a Restricted Subsidiary,
and (b) after giving effect thereto, the Cash Flow Ratio shall be less than or
equal to 9 to 1.
    
 
    The foregoing provisions of this covenant shall not prohibit (i) any renewal
or reclassification of any Investment existing on the date hereof or (ii) trade
credit extended on usual and customary terms in the ordinary course of business.
 
   
    TRANSACTIONS WITH AFFILIATES.  The Indentures provide that the Company shall
not, and shall not permit any of its subsidiaries to, sell, lease, transfer or
otherwise dispose of any of its properties or assets to or purchase any property
or assets from, or enter into any contract, agreement, understanding, loan,
advance or guarantee with, or for the benefit of, an Affiliate of the Company
that is not a subsidiary of the Company, having a value, or for consideration
having a value, in excess of $10,000,000 individually or in the aggregate unless
the Board of Directors of the Company shall make a good faith determination that
the terms of such transaction are, taken as a whole, no less favorable to the
Company or such subsidiary, as the case may be, than those which might be
available in a comparable transaction with an unrelated Person. For purposes of
clarification, this provision shall not apply to Restricted Payments permitted
under "Limitation on Restricted Payments".
    
 
    COVENANTS APPLICABLE TO SENIOR DEBT SECURITIES.  Unless otherwise specified
in the applicable Prospectus Supplement, the following covenant contained in the
Senior Indenture shall be applicable with respect to any series of Senior Debt
Securities:
 
    LIMITATION ON LIENS.  The Senior Indenture provides that the Company shall
not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
create, incur, assume or suffer to exist any Lien of any kind, except for
Permitted Liens, on or with respect to any of its property or assets, whether
owned at the date of the Senior Indenture or thereafter acquired, or any income,
profits or proceeds therefrom, or assign or otherwise convey any right to
receive income thereon, unless (x) in the case of any Lien securing Indebtedness
that is subordinated in right of payment to the Senior Debt Securities of the
series offered pursuant to such Prospectus Supplement, the Senior Debt
Securities of such series are secured by a Lien on such property, assets or
proceeds that is senior in priority to such Lien and (y) in the case of any
other Lien, the Senior Debt Securities of such series are equally and ratably
secured.
 
    COVENANTS APPLICABLE TO SUBORDINATED DEBT SECURITIES.  Unless otherwise
specified in the applicable Prospectus Supplement, the following covenant
contained in the Subordinated Indenture shall be applicable with respect to any
series of Subordinated Debt Securities:
 
   
    LIMITATION ON SENIOR SUBORDINATED INDEBTEDNESS.  The Subordinated Indenture
provides that the Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become liable for, contingently or otherwise, or become responsible
for the payment of, contingently or otherwise, any Indebtedness which is both
(i) senior in right of payment to the Subordinated Debt Securities of any series
and (ii) expressly subordinate in right of payment to any
    
 
                                       21
<PAGE>
   
other Indebtedness of the Company. For purposes of this covenant, Indebtedness
is deemed to be senior in right of payment of the Subordinated Debt Securities
of a series if it is not subordinate in right of payment to Senior Indebtedness
at least to the same extent as such Subordinated Debt Securities are subordinate
to Senior Indebtedness.
    
 
    If so indicated in the applicable Prospectus Supplement with respect to a
particular series of Debt Securities, the Company will be subject to the
covenants described therein.
 
EVENTS OF DEFAULT
 
   
    The following are Events of Default under the Indentures with respect to
Debt Securities of any series (unless they are inapplicable to such series of
Debt Securities or they are specifically deleted in the supplemental indenture
or Board Resolution under which such series of Debt Securities is issued or has
been modified): (a) default for 30 days in payment of interest on any Debt
Security; (b) default in payment of principal or premium, if any, of any Debt
Security at maturity, upon acceleration, redemption or otherwise; (c) default in
the deposit of any sinking fund payment when and as due; (d) failure to comply
with any other covenant or agreement of the Company, continued for 60 days (or,
with respect to certain covenants or agreements, 30 days) after written notice
as provided in the Indentures; (e) a default or defaults under any mortgage,
indenture or instrument which secures or evidences any Indebtedness for money
borrowed or guaranteed by the Company or a Restricted Subsidiary in an aggregate
amount of $10,000,000 or more (but excluding any Indebtedness for the deferred
purchase price of property or services owed to the Person providing such
property or services as to which the Company or such Restricted Subsidiary is
contesting its obligation to pay the same in good faith and by proper
proceedings and for which the Company or such Restricted Subsidiary has
established appropriate reserves) which result from the failure to pay such
Indebtedness at final maturity or which have resulted in the acceleration of
such Indebtedness; (f) the entry of a final judgment or final judgments for the
payment of money by a court or courts of competent jurisdiction against the
Company or any Restricted Subsidiary in an aggregate amount exceeding
$10,000,000, which remain undischarged and unbonded for a period (during which
execution shall not be effectively stayed) of 60 days or as to which an
enforcement proceeding has been commenced by any creditor; (g) certain events of
bankruptcy, insolvency or reorganization; and (h) any other Event of Default as
may be specified for such series.
    
 
   
    If an Event of Default (other than as specified in (g) above) shall occur
and be continuing under the Indenture applicable to any series of Debt
Securities, either the Trustee with respect to such series or the Holders of not
less than 25% in aggregate principal amount of the outstanding Debt Securities
of such series by written notice to the Company (and to the Trustee if such
notice is given by the Holders) and, in the case of Subordinated Debt
Securities, the agents, if any, under the Credit Agreement, may declare all the
unpaid principal of, premium, if any, and interest on the Debt Securities of
such series to be due and payable as provided in the applicable Indenture. Upon
a declaration of acceleration with respect to a series outstanding under the
applicable Indenture (or of all series, as the case may be), such principal,
premium, if any, and accrued interest shall be due and payable upon the first to
occur of an acceleration under the Credit Agreement or ten days after receipt by
the Company and, in the case of Subordinated Debt Securities, the agents, if
any, under the Credit Agreement, of such written notice. No action on the part
of the Trustee or any Holder of the Debt Securities of any series is required
for such acceleration if an Event of Default specified in (g) above shall occur
and be continuing. The Holders of at least a majority in principal amount of the
Debt Securities of any series then outstanding may rescind an acceleration and
its consequences if (i) all existing Events of Default, other than the
nonpayment of principal of, premium, if any, or interest on the Debt Securities
of such series which have become due solely because of the acceleration, have
been cured or waived and (ii) the rescission would not conflict with any
judgment or decree of a court of competent jurisdiction. A declaration of
acceleration because of an Event of Default specified in clause (e) of the
preceding paragraph would be automatically annulled if the Indebtedness referred
to therein were discharged, or the Holders thereof rescinded their declaration
of acceleration referred to therein, within 30 days after the acceleration of
the Debt Securities of such series and no other
    
 
                                       22
<PAGE>
Event of Default had occurred and not been cured or waived during such period.
The Holders of a majority in principal amount of the Debt Securities of any
series outstanding also have the right to waive certain past defaults under the
Indentures.
 
   
    No Holder of Debt Securities of any series issued under either Indenture has
any right to institute any proceeding with respect to the Debt Securities of
such series, such Indenture or for any remedy thereunder, unless (i) such Holder
has previously given to the applicable Trustee written notice of a continuing
Event of Default under such Indenture, (ii) with respect to certain Events of
Default designated in the Prospectus Supplement related to a series of Debt
Securities, the Holders of at least 25% in principal amount of the outstanding
Debt Securities of such series issued under such Indenture have made written
request and offered reasonable indemnity to the Trustee to institute such
proceeding as Trustee under such Indenture, and (iii) with respect to certain
Events of Default designated in the Prospectus Supplement related to a series of
Debt Securities, the Trustee with respect to that series has not received from
the Holders of a majority in principal amount of the outstanding Debt Securities
of such series a direction inconsistent with such request and the Trustee has
failed to institute such proceeding within 60 days after receipt of such notice.
Such limitations do not apply, however, to a suit instituted by a Holder of a
Debt Security of a series for the enforcement of payment of the principal of or
premium, if any, or interest on such Debt Security on or after the respective
due dates expressed in such Debt Security.
    
 
   
    During the existence of an Event of Default, the applicable Trustee is
required to exercise such rights and powers vested in it under the related
Indenture and use the same degree of care and skill in its exercise thereof as a
prudent person would exercise under the circumstances in the conduct of such
person's own affairs. Subject to the provisions of the applicable Indenture
relating to the duties of the Trustee thereunder, in case an Event of Default
shall occur and be continuing, the Trustee is not under any obligation to
exercise any of its rights or powers under such Indenture at the request or
direction of any of the Holders unless such Holders shall have offered to the
Trustee reasonable security or indemnity. Subject to such provisions for the
indemnification of the Trustee, the Holders of a majority in principal amount of
the outstanding Debt Securities of any series have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee under the
applicable Indenture.
    
 
   
    The Company is required to furnish to each Trustee an annual statement as to
the performance by the Company of its obligations under the applicable Indenture
and as to any default in such performance.
    
 
SATISFACTION AND DISCHARGE OF THE INDENTURES AND THE DEBT SECURITIES
 
   
    The Indentures will cease to be of further effect (except as to surviving
rights of registration of transfer or exchange of Debt Securities of any series
outstanding under the applicable Indenture, as expressly provided for therein)
as to such series when either (i) all Debt Securities of such series outstanding
thereunder theretofore authenticated and delivered (except for lost, stolen or
destroyed Debt Securities of such series which have been replaced or paid) have
been delivered to the applicable Trustee for cancellation and the Company has
paid all sums payable by it under the related Indenture or (ii) all Debt
Securities of such series not theretofore delivered to the related Trustee for
cancellation (a) have become due and payable, or (b) will become due and payable
within one year, or (c) are to be called for redemption within one year, and the
Company has irrevocably deposited or caused to be deposited with such Trustee
funds in an amount sufficient to pay the entire indebtedness on the Debt
Securities of such series not theretofore delivered to such Trustee for
cancellation, for principal (and premium, if any) and interest to the date of
deposit (if the Debt Securities of such series are then due and payable) or to
the applicable maturity or redemption date (as the case may be), and the Company
has paid all other sums payable by it under the applicable Indenture.
    
 
MODIFICATION AND WAIVER
 
    Modifications and amendments of the applicable Indenture or the Debt
Securities of any series may be made by the Company and the applicable Trustee
with the consent of the Holders of not less than a
 
                                       23
<PAGE>
majority in aggregate principal amount of the outstanding Debt Securities of
such series; PROVIDED, HOWEVER, that no such modification or amendment may,
without the consent of the Holder of each outstanding Debt Security of such
series, (i) change the stated maturity of the principal of, or premium, if any,
or any installment of interest on, any Debt Securities of such series, (ii)
reduce the principal amount of, or the premium, if any, or interest on, the Debt
Securities of such series, (iii) change the coin or currency in which any Debt
Securities of such series or any premium or the interest thereon is payable,
(iv) impair the right to institute suit for the enforcement of any payment on or
with respect to the Debt Securities of such series, (v) reduce the percentage in
principal amount of outstanding Debt Securities of such series necessary to
waive compliance with certain provisions of the applicable Indenture or to waive
certain defaults, (vi) modify any of the provisions relating to supplemental
indentures requiring the consent of Holders or relating to the waiver of past
defaults, except to increase the percentage of outstanding Debt Securities of
such series required for such actions or to provide that certain other
provisions of the applicable Indenture cannot be modified or waived without the
consent of the Holder of each Debt Security of such series affected thereby, or
(vii) modify any of the provisions of the Indenture applicable to a series of
Subordinated Debt Securities relating to the subordination of the Subordinated
Debt Securities of such series in a manner adverse to the Holders thereof.
 
    The Holders of a majority in aggregate principal amount of the Debt
Securities of any series then outstanding under any Indenture may waive
compliance with certain restrictive covenants and provisions of such Indenture.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
   
    The Company may not consolidate or merge with or into, or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
assets to, any Person, unless: (i) the entity formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or disposition shall have been made
shall be a corporation organized and existing under the laws of the United
States, any State thereof or the District of Columbia, and shall assume by a
supplemental indenture all the obligations of the Company under the Outstanding
Debt Securities and the Indentures; (ii) immediately before and immediately
after such transaction, after giving effect thereto, no Default or Event of
Default shall have occurred and be continuing; and (iii) immediately after such
transaction, and after giving effect thereto, the Person formed by or surviving
any such consolidation or merger or to which such sale, assignment, transfer,
lease or conveyance or disposition shall have been made shall have a Cash Flow
Ratio not in excess of 9 to 1.
    
 
DEFEASANCE
 
    Unless the Prospectus Supplement relating to the Offered Debt Securities
otherwise provides, the Company at its option at any time may terminate all of
its obligations with respect to the Debt Securities of any series
("defeasance"), except for certain obligations, including those regarding the
Defeasance Trust (as defined below) and obligations to register the transfer or
exchange of the Debt Securities of such series, to replace mutilated, destroyed,
lost or stolen Debt Securities of such series and to maintain agencies in
respect of the Debt Securities of such series. The Company may also at any time
terminate its obligations under the covenants set forth in the applicable
Indenture, which are described under "Certain Covenants of the Company", and any
omission to comply with such obligations shall not constitute a Default or an
Event of Default with respect to the Debt Securities of such series ("covenant
defeasance").
 
    In order to exercise either defeasance or covenant defeasance, (i) the
Company must irrevocably deposit in trust, for the benefit of the Holders, with
the applicable Trustee money or U.S. government obligations, or a combination
thereof, in such amounts as will be sufficient to pay the principal of and
premium, if any, and interest on the Debt Securities of such series to
redemption or maturity (the "Defeasance Trust"), (ii) the Company must deliver
opinions of counsel to the effect that such Holders will not recognize income,
gain or loss for federal income tax purposes as a result of such defeasance or
covenant defeasance and will be subject to federal income tax on the same
amounts, in the same manner
 
                                       24
<PAGE>
and at the same times as would have been the case if such defeasance or covenant
defeasance had not occurred (in the case of defeasance, such opinion must refer
to and be based upon a ruling of the Internal Revenue Service or a change in
applicable federal income tax laws), (iii) the Company must comply with certain
other conditions, and (iv) in the case of Subordinated Debt Securities, no event
or condition shall exist that, pursuant to certain provisions described under
"Subordination of Subordinated Debt Securities" below, would prevent the Company
from making payments of principal of and premium, if any, and interest on the
Debt Securities of such series at the date of the irrevocable deposit referred
to above or at any time during the period ending on the 91st day after such
deposit date.
 
SUBORDINATION OF SUBORDINATED DEBT SECURITIES
 
    Unless otherwise indicated in the Prospectus Supplement, the following
provisions will apply to the Subordinated Debt Securities.
 
    The indebtedness represented by the Subordinated Debt Securities is
subordinated in right of payment to the prior payment in full of all Senior
Indebtedness.
 
    Upon the maturity of any Senior Indebtedness, by lapse of time, acceleration
or otherwise, or upon any payment default (with or without the giving of notice
or lapse of time or both in accordance with the terms of the instrument
governing such Senior Indebtedness, and without any waiver or forgiveness) with
respect to any Senior Indebtedness, all obligations with respect to such Senior
Indebtedness must first be paid in full, or such payment duly provided for,
before any payment is made with respect to the Subordinated Debt Securities of
any series or before any acquisition of Subordinated Debt Securities of any
series by the Company.
 
   
    Upon (i) a default with respect to any Senior Indebtedness (other than under
circumstances when the terms of the previous paragraph are applicable), as such
default is defined therein or in the instrument under which it is outstanding,
permitting the holders of Senior Indebtedness to accelerate the maturity
thereof, and (ii) written notice thereof ("Default Notice") given to the Company
and the Subordinated Trustee by the agent or agents under the Credit Agreement,
then, unless and until such default shall have been cured or waived by the
holders of such Senior Indebtedness or shall have ceased to exist, no direct or
indirect payment may be made by the Company with respect to the principal of,
premium, if any, or interest on the Subordinated Debt Securities (other than
payments made in Junior Securities) or to acquire any of the Subordinated Debt
Securities or on account of the redemption provisions of the Subordinated Debt
Securities (except mandatory redemption payments made, in accordance with the
terms of the Subordinated Debt Securities, in Subordinated Debt Securities
acquired by the Company before the Default Notice): PROVIDED, HOWEVER, that such
provision shall not prevent the making of any payment (which is not otherwise
prohibited by the previous paragraph) for more than 120 days after the Default
Notice shall have been given unless the Senior Indebtedness in respect of which
such event of default exists has been declared due and payable in its entirety,
in which case no such payment may be made until such acceleration has been
rescinded or annulled or such Senior Indebtedness has been paid in full.
Notwithstanding the foregoing, not more than one Default Notice may be given
with respect to Senior Indebtedness within a period of 240 consecutive days.
    
 
    The Subordinated Indenture will provide that, upon any payment by or
distribution of the assets of the Company to creditors upon any dissolution,
winding up, liquidation bankruptcy, reorganization, assignment for the benefit
of creditors, or any insolvency, receivership or similar proceeding relating to
the Company, all Senior Indebtedness must be paid in full, or such payment duly
provided for, before any payment or distribution (other than in Junior
Securities) is made on account of the principal of or premium, if any, or
interest on the Subordinated Debt Securities of any series.
 
    By reason of such subordination, in the event of liquidation or insolvency,
creditors of the Company who are holders of Senior Indebtedness may recover
more, ratably, than other creditors of the Company and creditors of the Company
who are not holders of Senior Indebtedness or of the Subordinated Debt
Securities may recover more, ratably, than the Holders of the Subordinated Debt
Securities.
 
                                       25
<PAGE>
    A Holder of Subordinated Debt Securities by his acceptance of Subordinated
Debt Securities agrees to be bound by such provisions and authorizes and
expressly directs the Subordinated Trustee, on his behalf to take such action as
may be necessary or appropriate to effectuate the subordination provided for in
the Subordinated Indenture and appoints the Subordinated Trustee his
attorney-in-fact for such purpose.
 
    The Subordinated Indenture does not limit or prohibit the incurrence of
additional Senior Indebtedness, which may include indebtedness that is senior to
the Subordinated Debt Securities, but subordinate to other obligations of the
Company. The Senior Debt Securities, when issued, will constitute Senior
Indebtedness.
 
    The Prospectus Supplement may further describe the provisions, if any,
applicable to the subordination of the Subordinated Debt Securities of a
particular series.
 
GOVERNING LAW
 
    The Indentures and the Debt Securities will be governed by, and construed in
accordance with, the laws of the State of New York.
 
REGARDING THE TRUSTEES
 
    The Indentures contain certain limitations on the right of the respective
Trustees, should they become a creditor of the Company, to obtain payment of
claims in certain cases, or to realize for their own accounts on certain
property received in respect of any such claim as security or otherwise. The
Trustees will be permitted to engage in certain other transactions; however, if
they acquire any conflicting interest and there is a default under the Debt
Securities, they must eliminate such conflict or resign.
 
    Any Trustee may resign or be removed with respect to one or more series of
Debt Securities and a successor Trustee may be appointed to act with respect to
such series. In the event that two or more persons are acting as Trustee with
respect to different series of Debt Securities, each such Trustee shall be a
Trustee of a trust under the related Indenture separate and apart from the trust
administered by any other such Trustee, and any action described herein to be
taken by the "Trustee" may then be taken by each such Trustee with respect to,
and only with respect to, the one or more series of Debt Securities for which it
is Trustee.
 
                              PLAN OF DISTRIBUTION
 
    The Company may sell the Debt Securities to one or more underwriters for
public offering and sale by them or may sell the Debt Securities to investors
directly or through agents. Any such underwriter or agent involved in the offer
and sale of the Debt Securities will be named in the related Prospectus
Supplement. The Company has reserved the right to sell the Debt Securities
directly to investors on its own behalf in those jurisdictions where it is
authorized to do so.
 
    Underwriters may offer and sell the Debt Securities at a fixed price or
prices that may be changed, at market prices prevailing at the time of sale, at
prices related to such prevailing market prices or at negotiated prices. The
Company also may, from time to time, authorize dealers, acting as the Company's
agents, to offer and sell the Debt Securities upon such terms and conditions as
set forth in the related Prospectus Supplement. In connection with the sale of
the Debt Securities, underwriters may receive compensation from the Company in
the form of underwriting discounts or commissions and may also receive
commissions from purchasers of the Debt Securities for whom they may act as
agent. Underwriters may sell the Debt Securities to or through dealers, and such
dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions (which may be changed from
time to time) from the purchasers for whom they may act as agents.
 
    Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of the Debt Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the related Prospectus Supplement. Dealers and agents
 
                                       26
<PAGE>
participating in the distribution of the Debt Securities may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the Debt Securities may be deemed to be
underwriting discounts and commissions under the Securities Act. Underwriters,
dealers and agents may be entitled, under agreements entered into with the
Company, to indemnification against and contribution towards certain civil
liabilities, including any liabilities under the Securities Act.
 
    Until the distribution of the Debt Securities is completed, rules of the
Commission may limit the ability of the Underwriters to bid for and purchase the
Debt Securities. As an exception to these rules, the Underwriters are permitted
to engage in certain transactions that stabilize the price of the Debt
Securities. Such transactions consist of bids or purchases for the purpose of
pegging, fixing or maintaining the price of the Debt Securities. If the
Underwriters create a short position in the Debt Securities in connection with
the offering, I.E., if they sell more Debt Securities than are set forth on the
cover page of the applicable Prospectus Supplement, the Underwriters may reduce
that short position by purchasing Debt Securities in the open market. The
Underwriters may also impose a penalty bid on certain Underwriters. This means
that if the Underwriters purchase the Debt Securities in the open market to
reduce the Underwriters' short position or to stabilize the price of the Debt
Securities, they may reclaim the amount of the selling concession from the
Underwriters who sold those shares as part of the offering. In general,
purchases of a security for the purpose of stabilization or to reduce a short
position could cause the price of the security to be higher than it might be in
the absence of such purchases. The imposition of a penalty bid might also have
an effect on the price of a security to the extent that it were to discourage
resales of the security.
 
    Any Debt Securities issued hereunder will be new issues of securities with
no established trading market. Any underwriters or agents to or through whom
such Debt Securities are sold by the Company for public offering and sale may
make a market in such Debt Securities, but such underwriters or agents will not
be obligated to do so and may discontinue any market at any time without notice.
No assurance can be given as to the liquidity of the trading market for any such
Debt Securities.
 
    Certain of the underwriters, dealers or agents and their associates may
engage in transactions with, and perform services for, the Company and certain
of its affiliates in the ordinary course of business.
 
                        VALIDITY OF THE DEBT SECURITIES
 
    The validity of any Debt Securities issued hereunder will be passed upon for
the Company by Sullivan & Cromwell, New York, New York, counsel to the Company.
The validity of any Debt Securities issued hereunder will be passed upon for any
underwriters by Shearman & Sterling, New York, New York.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers as well as other employees and
individuals against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement in connection with specified actions, suits or
proceedings, whether civil, criminal, administrative or investigative (other
than an action by or in the right of the corporation--a "derivative action"), if
they acted in good faith and in a manner they reasonably believed to be in or
not opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe their conduct
was unlawful. A similar standard is applicable in the case of derivative
actions, except that indemnification only extends to expenses (including
attorneys' fees) incurred in connection with defense or settlement of such
action, and the statute requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation. The statute provides that it is not exclusive of other
rights to which those seeking indemnification may be entitled under any by-law,
agreement, vote of stockholders or disinterested directors or otherwise.
 
    The first paragraph of Article Ninth of the Company's Certificate of
Incorporation provides:
 
        The corporation shall, to the fullest extent permitted by Section 145 of
    the General Corporation Law of the State of Delaware, as the same may be
    amended and supplemented, or by any successor thereto, indemnify any and all
    persons whom it shall have power to indemnify under said section from and
    against any and all of the expenses, liabilities or other matters referred
    to in or covered by said section. Such right to indemnification shall
    continue as to a person who has ceased to be a director, officer, employee
    or agent and shall inure to the benefit of the heirs, executors and
    administrators of such a person. The indemnification provided for herein
    shall not be deemed exclusive of any other rights to which those seeking
    indemnification may be entitled under any By-Law, agreement, vote of
    stockholders or disinterested directors or otherwise.
 
    Article VIII of the By-Laws of the Company provides:
 
        A. The corporation shall indemnify each person who was or is made a
    party or is threatened to be made a party to or is involved in any
    threatened, pending or completed action, suit or proceeding, whether civil,
    criminal, administrative or investigative (hereinafter a "proceeding"), by
    reason of the
 
                                      II-1
<PAGE>
    fact that he or she, or a person of whom he or she is the legal
    representative, is or was a director or officer of the corporation or is or
    was serving at the request of the corporation as a director, officer,
    employee or agent of another corporation or of a partnership, joint venture,
    trust or other enterprise, including service with respect to employee
    benefit plans, whether the basis of such proceeding is alleged action in an
    official capacity as a director, officer, employee or agent or alleged
    action in any other capacity while serving as a director, officer, employee
    or agent, to the maximum extent authorized by the Delaware General
    Corporation Law, as the same exists or may hereafter be amended (but, in the
    case of any such amendment, only to the extent that such amendment permits
    the corporation to provide broader indemnification rights than said law
    permitted the corporation to provide prior to such amendment), against all
    expense, liability and loss (including attorney's fees, judgments, fines,
    ERISA excise taxes or penalties and amounts paid or to be paid in
    settlement) reasonably incurred by such person in connection with such
    proceeding. Such indemnification shall continue as to a person who has
    ceased to be a director, officer, employee or agent and shall inure to the
    benefit of his or her heirs, executors and administrators. The right to
    indemnification conferred in this Article shall be a contract right and
    shall include the right to be paid by the corporation the expenses incurred
    in defending any such proceeding in advance of its final disposition;
    PROVIDED that, if the Delaware General Corporation Law so requires, the
    payment of such expenses incurred by a director or officer in advance of the
    final disposition of a proceeding shall be made only upon receipt by the
    corporation of an undertaking by or on behalf of such person to repay all
    amounts so advanced if it shall ultimately be determined that such person is
    not entitled to be indemnified by the corporation as authorized in this
    Article or otherwise.
 
        B.  The right to indemnification and advancement of expenses conferred
    on any person by this Article shall not limit the corporation from providing
    any other indemnification permitted by law nor shall it be deemed exclusive
    of any other right which any such person may have or hereafter acquire under
    any statute, provision of the Certificate of Incorporation, by-law,
    agreement, vote of stockholders or disinterested directors or otherwise.
 
        C.  The corporation may purchase and maintain insurance, at its expense,
    to protect itself and any director, officer, employee or agent of the
    corporation or another corporation, partnership, joint venture, or other
    enterprise against any expense, liability or loss, whether or not the
    corporation would have the power to indemnify such person against such
    expense, liability or loss under the Delaware General Corporation Law.
 
    The Company has entered into indemnification agreements with certain of its
officers and directors indemnifying such officers and directors from and against
certain expenses, liabilities or other matters referred to in or covered by
Section 145 of the Delaware General Corporation Law. The Company has also
entered into an agreement with Charles F. Dolan ("Mr. Dolan"), the Chairman of
the Company, pursuant to which Mr. Dolan has agreed to guarantee the Company's
obligation to indemnify its officers and directors to the fullest extent
permitted by Delaware law. In addition, subject to certain limitations, Mr.
Dolan has agreed to indemnify such officers and directors against any loss or
expense such person may incur in connection with any transaction involving Mr.
Dolan or entities affiliated with Mr. Dolan to the extent indemnification is not
provided by the Company. Any payment required to be made by Mr. Dolan pursuant
to such agreement will be reduced by any proceeds of insurance or reimbursement
under any other form of indemnification reimbursement available to such officer
or director. The Company maintains directors' and officers' liability insurance.
 
    Section 102(b)(7) of the Delaware General Corporation Law permits a
corporation to provide in its certificate of incorporation that a director of
the corporation shall not be personally liable to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) for
payments of unlawful dividends or unlawful stock repurchases or redemptions, or
(iv) for any
 
                                      II-2
<PAGE>
transaction from which the director derived an improper personal benefit. The
second paragraph of Article Ninth of the Company's Certificate of Incorporation
provides for such limitation of liability.

ITEM 17. UNDERTAKINGS.
 
        The undersigned registrant hereby undertakes:
 
           (1) To file, during any period in which offers or sales are being
       made, a post-effective amendment to this Registration Statement:
 
               (i) To include any prospectus required by Section 10(a)(3) of the
           Securities Act;
 
               (ii) To reflect in the prospectus any facts or events arising
           after the effective date of the Registration Statement (or the most
           recent post-effective amendment thereof) which, individually or in
           the aggregate, represent a fundamental change in the information set
           forth in the Registration Statement;
 
               (iii) To include any material information with respect to the
           plan of distribution not previously disclosed in the Registration
           Statement or any material change to such information in the
           Registration Statement;
 
           PROVIDED, HOWEVER, that paragraphs (i) and (ii) do not apply if the
       information required to be included in a post-effective amendment by
       those paragraphs is contained in periodic reports filed by the Company
       pursuant to Section 13 or Section 15(d) of the Exchange Act that are
       incorporated by reference in the Registration Statement.
 
           (2) That, for the purpose of determining any liability under the
       Securities Act, each such post-effective amendment shall be deemed to be
       a new registration statement relating to the securities offered therein,
       and the offering of such securities at that time shall be deemed to be
       the initial bona fide offering thereof.
 
                                      II-3
<PAGE>
           (3) To remove from registration by means of a post-effective
       amendment any of the securities being registered which remain unsold at
       the termination of the offering.
 
           (4) The undersigned registrant hereby undertakes that, for purposes
       of determining any liability under the Securities Act of 1933, each
       filing of the registrant's annual report pursuant to Section 13(a) or
       15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
       filing of an employee benefit plan's annual report pursuant to Section
       15(d) of the Securities Exchange Act of 1934) that is incorporated by
       reference in the registration statement shall be deemed to be a new
       registration statement relating to the securities offered therein, and
       the offering of such securities at that time shall be deemed to be the
       initial bona fide offering thereof.
 
           (5) Insofar as indemnification for liabilities arising under the
       Securities Act of 1933 may be permitted to directors, officers and
       controlling persons of the registrant, pursuant to the provisions
       described in Item 15 or otherwise, the registrant has been advised that
       in the opinion of the Securities and Exchange Commission such
       indemnification is against public policy as expressed in the Securities
       Act of 1933 and is, therefore, unenforceable. In the event that a claim
       for indemnification against such liabilities (other than the payment by
       the registrant of expenses incurred or paid by a director, officer or
       controlling person of the registrant in the successful defense of any
       action, suit or proceeding) is asserted by any such director, officer or
       controlling person in connection with the securities being registered,
       the registrant will, unless in the opinion of its counsel the matter has
       been settled by controlling precedent, submit to a court of appropriate
       jurisdiction the question of whether or not such indemnification is
       against public policy as expressed in the Securities Act of 1933 and will
       be governed by the final adjudication of such issue.

    Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Amendment to the
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the Town of Oyster Bay and the State of New York, on the 26

the Trustee an Officers' Certificate stating that all conditions precedent, if
any, provided for in this Indenture (including any covenant compliance with
which constitutes a condition precedent) relating to the proposed action have
been complied with and an Opinion of Counsel stating that in the opinion of such

          (3)  a statement that, in the opinion of each such individual, he has

     individual, such covenant or condition has been complied with.

          SECTION 103.  FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

          In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

          Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

          SECTION 104.  ACTS OF HOLDERS.

          (a)  Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agents duly
appointed in writing.  If Securities of a series are issuable as Bearer
Securities, any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of such series may, alternatively, be embodied in and evidenced by the
record of Holders of Securities of such 

<PAGE>
                                          25


series voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record.  Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company.  Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting.  Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
TIA Section 315) conclusive in favor of the Trustee and the Company, if made in
the manner provided in this Section.  The record of any meeting of Holders of
Securities shall be proved in the manner provided in Section 1506.

          (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient.

          (c)  The ownership of Securities shall be proved by the Security
Register.

          (d)  The principal amount and serial numbers of Bearer Securities held
by any Person, and the date of holding the same, may be proved by the production
of such Bearer Securities or by a certificate executed, as depositary, by any
trust company, bank, banker or other depositary, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depositary, or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory.  The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding.  The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner that the Trustee deems
sufficient.

          (e)  If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, by or pursuant to a Board
Resolution, fix in advance a record date for the determination of such Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), any such record date shall be the 


<PAGE>
                                          26


record date specified in or pursuant to such Board Resolution, which shall be a
date not more than 30 days prior to the first solicitation of Holders generally
in connection therewith and no later than the date such solicitation is
completed.  If such a record date is fixed, such request, demand, authorization,
direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on
such record date shall be deemed to be Holders for the purposes of determining
whether Holders of the requisite proportion of Securities then Outstanding have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other Act, and for that purpose the
Securities then Outstanding shall be computed as of such record date; PROVIDED
that no such request, demand, authorization, direction, notice, consent, waiver
or other Act by the Holders on such record date shall be deemed effective unless
it shall become effective pursuant to the provisions of this Indenture not later
than six months after the record date.

          (f)  Any request, demand, authorization, direction, notice, consent,
waiver or other Act by the Holder of any Security shall bind every future Holder
of the same Security or the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done, suffered or omitted to be done by the Trustee, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
action is made upon such Security.

          SECTION 105.  NOTICES, ETC. TO TRUSTEE AND COMPANY.

          Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

          (1)  the Trustee by any Holder, the Agents of the Banks or the Company
     shall be sufficient for every purpose hereunder if made, given, furnished
     or delivered, in writing, to or with the Trustee at its Corporate Trust
     Office, Attention:  Corporate Trust Trustee Administration; or

          (2)  the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) if
     made, given, furnished or delivered, in writing, to the Company addressed
     to it c/o Cablevision Systems Corporation, One Media Crossways, Woodbury,
     New York 11797, Attention:  Secretary, or at any other address previously
     furnished in writing to the Trustee by the Company.

          SECTION 106.  NOTICE TO HOLDERS; WAIVER.

          Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder affected by such event,
at his address as it appears in the Security Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice.  In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders of Registered Securities or the sufficiency of any
notice to Holders of Bearer Securities given as provided.  Any notice mailed to
a Holder in the aforesaid manner shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

          In case, by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impractical to mail
notice of any event to Holders of Registered Securities when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be sufficient giving of such notice for every purpose hereunder.

          Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given to Holders of Bearer Securities if published in an
Authorized Newspaper in The City of New York and in such other city or cities as
may be specified in such Securities on a Business Day at least twice, the first
such publication to be not earlier than the earliest date, and not later than
the latest date, prescribed for the giving of such notice.  Any such notice
shall be deemed to have been given on the date of the first such publication.

          In case, by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause, it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of such notice with
respect to other Holders of Bearer Securities or the sufficiency of any notice
to Holders of Registered Securities given as provided herein.

<PAGE>
                                          28


          Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.


          Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

          SECTION 107.  CONFLICT OF ANY PROVISION OF INDENTURE WITH TRUST
INDENTURE ACT.

          If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by TIA Sections 310 to 318,
inclusive, or conflicts with any provision (an "incorporated provision")
required by or deemed to be included in this Indenture by operation of such TIA
Sections, such imposed duties or incorporated provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or excluded, as the case may
be.

          SECTION 108.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

          The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

          SECTION 109.  SUCCESSORS AND ASSIGNS.

          All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

          SECTION 110.  SEPARABILITY CLAUSE.

          In case any provision in this Indenture or in any Security or coupon
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

          SECTION 111.  BENEFITS OF INDENTURE.

          Nothing in this Indenture or in the Securities or coupons, express or
implied, shall give to any Person, other than the parties hereto, any
Authenticating Agent, any Paying Agent, any Securities Registrar, any holders of
Senior Indebtedness and their successors

equitable right, remedy or claim under this Indenture.

          SECTION 112.  GOVERNING LAW.

          This Indenture and the Securities and coupons shall be governed by 
and construed in accordance with the laws of the State of New York without 
regard to conflicts of laws principles.  This Indenture is subject to the 
provisions of the Trust Indenture Act that are required to be part of this 
Indenture and shall, to the extent applicable, be governed by such provisions.

          SECTION 113.  LEGAL HOLIDAYS.

          In any case where any Interest Payment Date, Redemption Date, sinking
fund payment date or Stated Maturity or Maturity of any Security shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of this Indenture or of any Security or coupon other than a provision in the
Securities of any series which specifically states that such provision shall
apply in lieu of this Section), payment of principal (or premium, if any) or
interest, if any, need not be made at such Place of Payment on such date, but
may be made on the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
PROVIDED that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

          SECTION 114.  NO RECOURSE AGAINST OTHERS.

          A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation.  Each Holder by accepting any of
the Securities waives and releases all such liability.

of identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange or as may,
consistently herewith, be determined by the officers executing such Securities
or coupons, as evidenced by their execution of the Securities or coupons.  If
the forms of Securities or coupons of any series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee at or prior to the delivery of the Company Order
contemplated by Section 303 for the authentication and delivery of such
Securities or coupons.  Any portion of the text of any Security may be set forth
on the reverse thereof, with an appropriate reference thereto on the face of the
Security.

in bearer form shall have interest coupons attached.

          The Trustee's certificate of authentication on all Securities shall be

                                                  as Trustee

          SECTION 203.  SECURITIES ISSUABLE IN GLOBAL FORM.

          If Securities of or within a series are issuable in global form, as
specified as contemplated by Section 301, then, any such Security shall
represent such of the Outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of Outstanding Securities of such series from time to time endorsed thereon and
that the aggregate amount of Outstanding Securities of such series represented
thereby may from time to time be increased or decreased to reflect exchanges. 
Any endorsement of a Security in global form to reflect the amount, or any
increase or decrease in the amount, of Outstanding Securities represented
thereby shall be made by the Trustee in such manner and upon instructions given
by such Person or Persons as shall be specified therein or in the Company Order
to be delivered to the Trustee pursuant to Section 303 or Section 305.  Subject
to the provisions of Section 303 and, if applicable, Section 305, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner
and upon instructions given by the Person or Persons specified therein or in the
applicable Company Order.  If a Company Order pursuant to Section 303 or Section
305 has been, or simultaneously is, delivered, any instructions by the Company

form shall be in writing but need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel.

          The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

<PAGE>
                                          32


          Notwithstanding the provisions of Section 308, unless otherwise
specified as contemplated by Section 301, payment of principal of (and premium,
if any) and interest, if any, on any Security in permanent global form shall be
made to the Person or Persons specified therein.

          Notwithstanding the provisions of Section 310 and except as provided
in the preceding paragraph, the Company, the Trustee and any agent of the
Company and the Trustee shall treat as the Holder of such principal amount of

          THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
     HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A
     NOMINEE THEREOF.  THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART

     of Default of the Company with respect to Securities of the series, whether

     limitations on such rights and preferences) relating to the series (which
     terms shall not be inconsistent with the requirements of the Trust
     Indenture Act or the provisions of this Indenture).

          All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto.  Not all Securities of any one series need be issued at the same time,
and, unless otherwise provided, a series may be reopened for issuances of
additional Securities of such series.

          If any of the terms of the series are established by action taken
pursuant to one or more Board Resolutions, such Board Resolutions shall be
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

          SECTION 302.  DENOMINATIONS.

          SECTION 303.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

          The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by any one of the following:  its Chairman, Chief
Executive Officer, its President or one of its Vice Presidents, and attested by
one of its Vice Presidents or its Secretary or one of its Assistant Secretaries.
The signature of any of these officers on the Securities or coupons may be
manual or facsimile.

          Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

          At any time and from time to time after the execution and delivery 
of this Indenture, the Company may deliver Securities of any series together 
with any coupon appertaining thereto, executed by the Company to the Trustee 
for authentication, together with a Company Order for the authentication and 
delivery of such Securities, and the Trustee in accordance with such Company 
Order shall authenticate and make available for delivery such Securities; 
PROVIDED, HOWEVER, that, in connection with its original issuance, no Bearer 
Security shall be mailed or otherwise delivered to any location in the United 
States; and PROVIDED FURTHER that, unless otherwise specified with respect to 
any series of Securities pursuant to Section 301, a Bearer Security may be 
delivered in connection with its original issuance only if the Person 
entitled to receive such Bearer Security shall have furnished a certificate 
in the form set forth in Exhibit B-1 to this Indenture, dated no earlier than 
15 days prior to the earlier of the date on which such Bearer Security is 
delivered and the date on which any temporary Security first becomes 
exchangeable for such Bearer Security in accordance with the terms of such 
temporary Security and this Indenture.  If any Security shall be represented 
by a permanent global Bearer Security, then, for purposes of this Section and 
Section 305, the notation of a beneficial owner's interest therein upon 
original issuance of such Security or upon exchange of a portion of a 
temporary Global Security shall be deemed to be delivery in connection with 
its original issuance of such beneficial owner's interest in such permanent 
Global Security.  Except as permitted by Section 307, the Trustee shall not 
authenticate and make available for delivery any Bearer Security unless all 
appurtenant coupons for interest then matured have been detached and 
cancelled.  If not all the Securities of any series are to be issued at one 
time and if the Board Resolution or supplemental indenture establishing such 
series shall so permit, such Company Order may set forth procedures 
acceptable to the Trustee for the issuance of such Securities and determining 
terms of particular Securities of such series such as interest rate, stated 
maturity, date of issuance and date from which interest shall accrue.

          In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, 

<PAGE>
                                          38


and (subject to TIA Sections 315(a) through 315(d)) shall be fully protected in
relying upon, an Opinion of Counsel stating:

          (a)  that the form or forms of such Securities and any coupons have
     been established in conformity with the provisions of this Indenture;

          (b)  that the terms of such Securities and any coupons have been
     established in conformity with the provisions of this Indenture;

          (c)  that such Securities, together with any coupons appertaining
     thereto, when completed by appropriate insertions and executed and
     delivered by the Company to the Trustee for authentication in accordance
     with this Indenture, authenticated and made available for delivery by the
     Trustee in accordance with this Indenture and issued by the Company in the
     manner and subject to any conditions specified in such Opinion of Counsel,
     will constitute the legal, valid and binding obligations of the Company,
     enforceable in accordance with their terms, subject to applicable
     bankruptcy, insolvency, reorganization and other similar laws of general
     applicability relating to or affecting the enforcement of creditors'
     rights, to general equitable principles and to such other qualifications as
     such counsel shall conclude do not materially affect the rights of Holders
     of such Securities and any coupons;

          (d)  that all laws and requirements in respect of the execution and
     delivery by the Company of such Securities, any coupons and of the
     supplemental indentures, if any, have been complied with and that
     authentication and delivery of such Securities and any coupons and the
     execution and delivery of the supplemental indenture, if any, by the
     Trustee will not violate the terms of the Indenture;

          (e)  that the Company has the corporate power to issue such Securities
     and any coupons, and has duly taken all necessary corporate action with
     respect to such issuance; and

          (f)  that the issuance of such Securities and any coupons will not
     contravene the articles of incorporation or by-laws of the Company or
     result in any violation of any of the terms or provisions of any law or
     regulation or of any indenture, mortgage or other agreement known to such
     Counsel by which the Company is bound.

          Notwithstanding the provisions of Section 301 and of the preceding two
paragraphs, if not all the Securities of any series are to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to the preceding two paragraphs prior to or at the
time of issuance of each Security, but such documents shall be delivered prior
to or at the time of issuance of the first Security of such series.

<PAGE>
                                          39


          The Trustee shall not be required to authenticate and make 
available for delivery any such Securities if the issue of such Securities 
pursuant to this Indenture will affect the Trustee's own rights, duties or 
immunities under the Securities and this Indenture or otherwise in a manner 
which is not reasonably acceptable to the Trustee.

          Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

          No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture. 
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 311 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of
this Indenture such Security shall be deemed never to have been authenticated
and delivered hereunder and shall never be entitled to the benefits of this
Indenture.

          SECTION 304.  BOOK-ENTRY SECURITIES.

          (a)  The Securities of a series may be issuable in whole or in part in
the form of one or more Global Securities ("Book-Entry Securities") deposited
with, or on behalf of, a Depository (the "Depository").  In the case of
Book-Entry Securities, one or more Global Securities will be issued in a
denomination or aggregate denomination equal to the portion of the aggregate
principal amount of Outstanding Securities of the series to be represented by
such Global Security or Global Securities.  Unless otherwise provided as
contemplated by Section 301, the additional provisions set forth in this Section
304 shall apply to Book-Entry Securities.

          (b)  Book-Entry Securities will be deposited with, or on behalf of,
the Depository, and registered in the name of the Depository's nominee, for
credit to the respective accounts of institutions that have accounts with the
Depository or its nominee ("Participants"); PROVIDED that Book-Entry Securities
purchased by persons outside the United States may be credited to or through
accounts maintained at the Depository by or on behalf of Euroclear or Cedel. 
The accounts to be credited will be designated by the underwriters or agents of
such Securities or, if such Securities are offered and sold directly by the
Company, by the Company.  Ownership of beneficial interests in Book-Entry
Securities will be limited 

<PAGE>
                                          40


to Persons that may hold interests through Participants and will be shown on
records maintained by the Depository or its nominee for such Book-Entry
Security.

          Participants shall have no rights under this Indenture or any
indenture supplemental hereto with respect to any Book-Entry Security held on
their behalf by the Depository, or the Trustee as its custodian, or under the
Book-Entry Security, and the Depository may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the
Book-Entry Security for all purposes whatsoever.  Notwithstanding the foregoing,
nothing in this Indenture or any such indenture supplemental shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Depository or impair, as between the Depository and its Participants, the
operation of customary practices governing the exercise of the rights of a
Holder of any Security.

          (c)  Transfers of Book-Entry Securities shall be limited to transfers
in whole, but not in part, to the Depository, its successors or their respective
nominees.  Interests of beneficial owners in Book-Entry Securities may be
transferred or exchanged for Bearer Securities only if (i) the Depository
advises the Trustee in writing that it is no longer willing or able to discharge
properly its responsibilities with respect to such Book-Entry Security and it is
unable to locate a qualified successor, (ii) the Company, at its option, elects
to terminate the book-entry system by executing and delivering to the Trustee
and the Depository a notice to such effect, or (iii) there shall have occurred
and be continuing a Default or Event of Default with respect to the Securities
represented by such Book-Entry Security.

          (d)  In connection with any transfer or exchange of a portion of the
beneficial interest in any Book-Entry Security to beneficial owners pursuant to
paragraph (c) above, the Security Registrar shall (if one or more Bearer
Securities are to be issued) reflect on its books and records the date and a
decrease in the principal amount of the Book-Entry Security in an amount equal
to the principal amount of the beneficial interest in the Book-Entry Security to
be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more Bearer Securities of like tenor and
principal amount of authorized denominations.

          (e)  In connection with the transfer of Book-Entry Securities as an
entirety to beneficial owners pursuant to paragraph (c) above, the Book-Entry
Securities shall be deemed to be surrendered to the Trustee for cancellation and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depository in exchange for its
beneficial interest in the Book-Entry Securities, an equal aggregate principal
amount of Bearer Securities of like tenor of authorized denominations.

<PAGE>
                                          41



          (f)  The Holder of any Book-Entry Security may grant proxies and
otherwise authorize any person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under the applicable Indenture or the Securities.


          SECTION 305.  TEMPORARY SECURITIES.

          Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are typewritten, printed, lithographed,
engraved or otherwise produced by any combination of these methods, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their
execution of such Securities.  Such temporary Securities may be in global form.

          Except in the case of temporary Securities in global form that are not
issued as Book-Entry Securities as provided in Section 304 (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay.  After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (accompanied by any unmatured coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations; PROVIDED, HOWEVER, that no Bearer Security shall be
delivered in exchange for a temporary Registered Security; and PROVIDED FURTHER
that a Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303.  Until
so exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

          If temporary Securities of any series are issued in global form (other
than Securities issued as Book-Entry Securities as provided in Section 304), any
such temporary Global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euroclear and Cedel, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

<PAGE>
                                          42


          Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security that is not issued as a Book-Entry Security as provided in Section 304
(the "Exchange Date"), the Company shall deliver to the Trustee definitive
Securities, in aggregate principal amount equal to the principal amount of such
temporary Global Security, executed by the Company.  On or after the Exchange
Date such temporary Global Security shall be surrendered by the Common
Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged.  The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof; PROVIDED,
HOWEVER, that, unless otherwise specified in such temporary Global Security,
upon such presentation by the Common Depositary, such temporary Global Security
is accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary Global Security held for
its account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by Cedel as to the portion of such temporary Global
Security held for its account then to be exchanged, each in the form set forth
in Exhibit B-2 to this Indenture (or in such other form as may be established
pursuant to Section 301); and PROVIDED FURTHER that Bearer Securities shall be
delivered in exchange for a portion of a temporary Global Security only in
compliance with the requirements of Section 303.

          Unless otherwise specified in such temporary Global Security that is
not issued as a Book-Entry Security as provided in Section 304, the interest of
a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
Cedel, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or Cedel, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and Cedel, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent.  Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euroclear or Cedel. 
Bearer Securities in bearer form to be delivered 

<PAGE>
                                          43


in exchange for any portion of a temporary Global Security shall be delivered
only outside the United States.

          Until exchanged in full as hereinabove provided, the temporary
Securities of any series, including temporary Global Securities (whether or not
issued as Book-Entry Securities as provided in Section 304), shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities of the same series and of like tenor authenticated and delivered
hereunder, except that, unless otherwise specified as contemplated by Section
301, interest payable on a temporary Global Security (other than Securities
issued as Book-Entry Securities as provided in Section 304) on an Interest
Payment Date for Securities of such series occurring prior to the applicable
Exchange Date shall be payable to Euroclear and Cedel on such Interest Payment
Date upon delivery by Euroclear and Cedel to the Trustee of a certificate or
certificates in the form set forth in Exhibit B-2 to this Indenture (or in such
other form as may be established pursuant to Section 301), for credit without
further interest thereon on or after such Interest Payment Date to the
respective accounts of the Persons who are the beneficial owners of such
temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or Cedel, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth in Exhibit B-1 to this Indenture (or in such
other form as may be established pursuant to Section 301).  Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section and of the third paragraph of Section 303 of this
Indenture and the interests of the Persons who are the beneficial owners of the
temporary Global Security with respect to which such certification was made will
be exchanged for definitive Securities of the same series and of like tenor on
the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal (or premium, if
any) or interest, if any, owing with respect to a beneficial interest in a
temporary Global Security will be made unless and until such interest in such
temporary Global Security shall have been exchanged for an interest in a
definitive Security.  Any interest so received by Euroclear and Cedel and not
paid as herein provided shall be returned to the Trustee immediately prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Company in accordance with Section 1003.

          SECTION 306.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

          The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register for each series of Securities (the registers maintained
in such office of the Trustee and in any other office or agency designated
pursuant to Section 1002 being herein sometimes referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Registered 

<PAGE>
                                          44


Securities and of transfers of Registered Securities.  The Trustee is hereby
initially appointed "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

          Except as otherwise described in this Article Three, upon surrender
for registration of transfer of any Registered Security of any series at the
office or agency in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series, in each case, of any authorized denominations and of a like
aggregate principal amount.

          At the option of the Holder, Registered Securities of any series 
may be exchanged for other Registered Securities of the same series, of any 
authorized denominations and of a like aggregate principal amount, upon 
surrender of the Registered Securities to be exchanged at such office or 
agency. Whenever any Registered Securities are so surrendered for exchange, 
the Company shall execute, and the Trustee shall authenticate and make 
available for delivery, the Registered Securities which the Holder making the 
exchange is entitled to receive.  Unless otherwise specified with respect to 
any series of Securities as contemplated by Section 301 or Section 304, 
Bearer Securities may not be issued in exchange for Registered Securities.

          If (but only if) expressly permitted in or pursuant to the applicable
Board Resolution and (subject to Section 303) set forth in the applicable
Officers' Certificate, or in any indenture supplemental hereto, delivered as
contemplated by Section 301, at the option of the Holder, Bearer Securities of
any series may be exchanged for Registered Securities of the same series of any
authorized denomination and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
with all unmatured coupons and all matured coupons in default thereto
appertaining.  If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, any such
permitted exchange may be effected if the Bearer Securities are accompanied by
payment in funds acceptable to the Company in an amount equal to the face amount
of such missing coupon or coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there is furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless.  If thereafter the Holder of such Security shall
surrender to any Paying Agent any such missing coupon in respect of which such a
payment shall have been made, such Holder shall be entitled to receive the
amount of such payment; PROVIDED, HOWEVER, that, except as otherwise provided in
Section 1002, interest represented by coupons shall be payable only upon
presentation and surrender of those coupons at an office or agency located
outside the United States.  Notwithstanding the foregoing, in case a Bearer
Security of any series is surrendered at any such office or agency in a
permitted exchange for a Registered Security of the same series and like tenor
after the close of business at such 

<PAGE>
                                          45


office or agency on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such office or
agency on the related proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

          Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive, and the Trustee
shall cancel the Bearer Securities so transferred.  In the case of an exchange
of Bearer Securities for an interest in a Book-Entry Security, the Security
Registrar shall reflect on the Register the date and an increase in the
principal amount of the Bearer Securities to be transferred, and the Trustee
shall cancel the Bearer Securities so transferred.

          Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security (other than
Securities issued as Book-Entry Securities as provided in Section 304) shall be
exchangeable only as provided in this paragraph.  If any beneficial owner of an
interest in a permanent Global Security is entitled to exchange such interest
for Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent Global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall deliver to the Trustee definitive Securities in aggregate
principal amount equal to the principal amount of such beneficial owner's
interest in such permanent Global Security, executed by the Company.  On or
after the earliest date on which such interests may be so exchanged, such
permanent Global Security shall be surrendered by the Common Depositary or such
other depositary as shall be specified in the Company Order with respect thereto
to the Trustee, as the Company's agent for such purpose, to be exchanged, in
whole or from time to time in part, for definitive Securities without charge,
and the Trustee shall authenticate and deliver, in exchange for each portion of
such permanent Global Security, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such permanent Global Security to be exchanged which,
unless the Securities of the series are not issuable both as Bearer Securities
and as Registered Securities, as specified as contemplated by Section 301, shall
be in the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof; PROVIDED,
HOWEVER, that no such exchanges may occur during a period beginning at the
opening of business 15 days before any selection of Securities to be 

<PAGE>
                                          46


redeemed and ending on the relevant Redemption Date if the Security for which
exchange is requested may be among those selected for redemption; and PROVIDED
FURTHER that no Bearer Security delivered in exchange for a portion of a
permanent Global Security shall be mailed or otherwise delivered to any location
in the United States.  If a Registered Security is issued in exchange for any
portion of a permanent Global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business
at such office or agency on the related proposed date for payment of Defaulted
Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent Global
Security is payable in accordance with the provisions of this Indenture.

          All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

          Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Security
Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer, in form satisfactory to the Company and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to pay all documentary, stamp, similar issue or transfer taxes or other
governmental charges that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to Section
305, 906, 1107 or 1305 not involving any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the selection for redemption of Securities
of that series under Section 1103 or 1203 and ending at the close of business on
(A) if Securities of the series are issuable only as Registered Securities, the
day of the mailing of the relevant notice of redemption and (B) if Securities of
the series are issuable as Bearer Securities, the day of the first publication
of the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part,
except the unredeemed portion of any 

<PAGE>
                                          47


Security being redeemed in part, or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of that series and like tenor; PROVIDED that such
Registered Security shall be simultaneously surrendered for redemption, or (iv)
to issue, register the transfer of or exchange any Security which has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

          SECTION 307.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

          If any mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee together with, in proper cases,
such security or indemnity as may be required by the Company or the Trustee to
save each of them and any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to the surrendered Security, or, in case
any such mutilated Security or coupon has become or is about to become due and
payable, the Company in its discretion may, instead of issuing a new Security,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security, pay such Security or coupon.

          If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon Company
Order the Trustee shall authenticate and deliver, in lieu of any such destroyed,
lost or stolen Security or in exchange for the Security for which a destroyed,
lost or stolen coupon appertains (with all appurtenant coupons not destroyed,
lost or stolen), a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to such destroyed,
lost or stolen Security or to the Security to which such destroyed, lost or
stolen coupon appertains.

          Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such mutilated, destroyed, lost or stolen Security or to the
Security to which such mutilated, destroyed, lost or stolen coupon appertains,
pay such Security or coupon; PROVIDED, HOWEVER, that payment of principal of
(and premium, if any) and interest, if any, on Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any 

<PAGE>
                                          48


interest on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto.

          Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to pay all documentary, stamp or
similar issue or transfer taxes or other governmental charges that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

          Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, destroyed, lost or
stolen coupon shall be at any time enforceable by anyone, and shall be entitled
to all the benefits of this Indenture equally and proportionately with any and
all other Securities of that series and their coupons, if any, duly issued
hereunder.

          The provisions of this Section 307 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

          SECTION 308.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED; OPTIONAL
INTEREST RESET.

          (a)  Unless otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest, if any, on any Registered
Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; PROVIDED, HOWEVER,
that each installment of interest, if any, on any Registered Security may at the
Company's option be paid by (i) mailing a check for such interest, payable to or
upon the written order of the Person entitled thereto pursuant to Section 310,
to the address of such Person as it appears on the Security Register or (ii)
transfer to an account located in the United States maintained by the payee.

          Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest, if any, may be made, in
the case of a Bearer Security, by transfer to an account located outside the
United States maintained by the payee.

          Unless otherwise provided as contemplated by Section 301, every
permanent Global Security (other than Book-Entry Securities issued as provided
in Section 304) will 

<PAGE>
                                          49


provide that interest, if any, payable on any Interest Payment Date will be paid
to each of Euroclear and Cedel with respect to that portion of such permanent
Global Security held for its account by the Common Depositary, for the purpose
of permitting each of Euroclear and Cedel to credit the interest, if any,
received by it in respect of such permanent Global Security to the accounts of
the beneficial owners thereof.

          Any interest on any Registered Security of any series which is
payable, but is not punctually paid or duly provided for, on any Interest
Payment Date shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and such defaulted
interest and, if applicable, interest on such defaulted interest (to the extent
lawful) at the rate specified in the Securities of such series (such defaulted
interest and, if applicable, interest thereon herein collectively called
"Defaulted Interest") may be paid by the Company, at its election in each case,
as provided in Subsection (1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
     to the Persons in whose names the Registered Securities of such series (or
     their respective Predecessor Securities) are registered at the close of
     business on a Special Record Date for the payment of such Defaulted
     Interest, which shall be fixed in the following manner.  The Company shall
     notify the Trustee in writing of the amount of Defaulted Interest proposed
     to be paid on each Registered Security of such series and the date of the
     proposed payment, and at the same time the Company shall deposit with the
     Trustee an amount of money in the Currency in which the Securities of such
     series are payable (except as otherwise specified pursuant to Section 301
     for the Securities of such series and except, if applicable, as provided in
     Sections 313(b), 313(d) and 313(e)) equal to the aggregate amount proposed
     to be paid in respect of such Defaulted Interest or shall make arrangements
     satisfactory to the Trustee for such deposit on or prior to the date of the
     proposed payment, such money when deposited to be held in trust for the
     benefit of the Persons entitled to such Defaulted Interest as in this
     Subsection provided.  Thereupon the Trustee shall fix a Special Record Date
     for the payment of such Defaulted Interest which shall be not more than 15
     days and not less than 10 days prior to the date of the proposed payment
     and not less than 10 days after the receipt by the Trustee of the notice of
     the proposed payment.  The Trustee shall promptly notify the Company of
     such Special Record Date and, in the name and at the expense of the
     Company, shall cause notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor to be given in the manner
     provided in Section 106, not less than 10 days prior to such Special Record
     Date.  Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been so given, such Defaulted Interest
     shall be paid to the Persons in whose name the Registered Securities of
     such series (or their respective Predecessor Securities) are registered at
     the close of business on such 

<PAGE>
                                          50


     Special Record Date and shall no longer be payable pursuant to the
     following Subsection (2).

          (2)  The Company may make payment of any Defaulted Interest on the
     Registered Securities of any series in any other lawful manner not
     inconsistent with the requirements of any securities exchange on which such
     Securities may be listed, and upon such notice as may be required by such
     exchange, if, after notice given by the Company to the Trustee of the
     proposed payment pursuant to this clause, such manner of payment shall be
     deemed practicable by the Trustee.

          (b)  The provisions of this Section 308(b) may be made applicable to
any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301). 
The interest rate (or the spread or spread multiplier used to calculate such
interest rate, if applicable) on any Security of such series may be reset by the
Company on the date or dates specified on the face of such Security (each an
"Optional Reset Date").  The Company may exercise such option with respect to
such Security by notifying the Trustee of such exercise at least 50 but not more
than 60 days prior to an Optional Reset Date for such Note, which such notice
shall contain such information as may be required by the Trustee to transmit the
Reset Notice as hereinafter defined).  Not later than 40 days prior to each
Optional Reset Date, the Trustee shall transmit, in the manner provided for in
Section 106, to the Holder of any such Security a notice (the "Reset Notice")
indicating whether the Company has elected to reset the interest rate (or the
spread or spread multiplier used to calculate such interest rate, if
applicable), and if so (i) such new interest rate (or such new spread or spread
multiplier, if applicable) and (ii) the provisions, if any, for redemption
during the period from such Optional Reset Date to the next Optional Reset Date
or if there is no such next Optional Reset Date, to the Stated Maturity Date of
such Security (each such period a "Subsequent Interest Period"), including the
date or dates on which or the period or periods during which and the price or
prices at which such redemption may occur during the Subsequent Interest Period.


          Notwithstanding the foregoing, not later than 20 days prior to the
Optional Reset Date, the Company may, at its option, revoke the interest rate
(or the spread or spread multiplier used to calculate such interest rate, if
applicable) provided for in the Reset Notice and establish an interest rate (or
a spread or spread multiplier used to calculate such interest rate, if
applicable) that is higher than the interest rate (or the spread or spread
multiplier, if applicable) provided for in the Reset Notice, for the Subsequent
Interest Period by causing the Trustee to transmit, in the manner provided for
in Section 106, notice of such higher interest rate (or such higher spread or
spread multiplier, if applicable) to the Holder of such Security.  Such notice
shall be irrevocable.  All Securities with respect to which the interest rate
(or the spread or spread multiplier used to calculate such interest rate, if
applicable) is reset on an Optional Reset Date, and with respect to which the
Holders of such Securities have not tendered such Securities for repayment (or
have validly revoked any such tender) 

<PAGE>
                                          51


pursuant to the next succeeding paragraph, will bear such higher interest rate
(or such higher spread or spread multiplier, if applicable).

          The Holder of any such Security will have the option to elect
repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest
accrued to such Optional Reset Date.  In order to obtain repayment on an
Optional Reset Date, the Holder must follow the procedures set forth in Article
Thirteen for repayment at the option of Holders except that the period for
delivery or notification to the Trustee shall be at least 25 but not more than
35 days prior to such Optional Reset Date and except that, if the Holder has
tendered any Security for repayment pursuant to the Reset Notice, the Holder
may, by written notice to the Trustee, revoke such tender or repayment until the
close of business on the tenth day before such Optional Reset Date.

          Subject to the foregoing provisions of this Section and Section 306,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

          SECTION 309.  OPTIONAL EXTENSION OF STATED MATURITY.

          The provisions of this Section 309 may be made applicable to any
series of Securities pursuant to Section 301 (with such modifications, additions
or substitutions as may be specified pursuant to such Section 301).  The Stated
Maturity of any Security of such series may be extended at the option of the
Company for the period or periods specified on the face of such Security (each
an "Extension Period") up to but not beyond the date (the "Final Maturity") set
forth on the face of such Security.  The Company may exercise such option with
respect to any Security by notifying the Trustee of such exercise at least 50
but not more than 60 days prior to the Stated Maturity of such Security in
effect prior to the exercise of such option (the "Original Stated Maturity"). 
If the Company exercises such option, the Trustee shall transmit, in the manner
provided for in Section 106, to the Holder of such Security not later than 40
days prior to the Original Stated Maturity a notice (the "Extension Notice")
indicating (i) the election of the Company to extend the Stated Maturity, (ii)
the new Stated Maturity, (iii) the interest rate, if any, applicable to the
Extension Period and (iv) the provisions, if any, for redemption during such
Extension Period.  Upon the Trustee's transmittal of the Extension Notice, the
Stated Maturity of such Security shall be extended automatically and, except as
modified by the Extension Notice and as described in the next paragraph, such
Security will have the same terms as prior to the transmittal of such Extension
Notice.

          Notwithstanding the foregoing, not later than 20 days before the
Original Stated Maturity of such Security, the Company may, at its option,
revoke the interest rate 

<PAGE>
                                          52


provided for in the Extension Notice and establish a higher interest rate for
the Extension Period by causing the Trustee to transmit, in the manner provided
for in Section 106, notice of such higher interest rate to the Holder of such
Security.  Such notice shall be irrevocable.  All Securities with respect to
which the Stated Maturity is extended will bear such higher interest rate.

          If the Company extends the Maturity of any Security, the Holder will
have the option to elect repayment of such Security by the Company on the
Original Stated Maturity at a price equal to the principal amount thereof, plus
interest accrued to such date.  In order to obtain repayment on the Original
Stated Maturity once the Company has extended the Maturity thereof, the Holder
must follow the procedures set forth in Article Thirteen for repayment at the
option of Holders, except that the period for delivery or notification to the
Trustee shall be at least 25 but not more than 35 days prior to the Original
Stated Maturity and except that, if the Holder has tendered any Security for
repayment pursuant to an Extension Notice, the Holder may by written notice to
the Trustee revoke such tender for repayment until the close of business on the
tenth day before the Original Stated Maturity.

          SECTION 310.  PERSONS DEEMED OWNERS.

          Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 306 and 308)
interest, if any, on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Trustee or
any agent of the Company or the Trustee shall be affected by notice to the
contrary.

          Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Company, the Trustee and any agent of the Company
or the Trustee may treat the bearer of any Bearer Security and the bearer of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupons be overdue, and none of the
Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

          None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

<PAGE>
                                          53


          Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such Global Security.

          SECTION 311.  CANCELLATION.

          All Securities and coupons surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange or
for credit against any current or future sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee. 
All Securities and coupons so delivered to the Trustee shall be promptly
cancelled by it.  The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee.  If the Company shall so acquire any of the
Securities, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Securities unless and until
the same are surrendered to the Trustee for cancellation.  No Securities shall
be authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture.  All
cancelled Securities held by the Trustee shall be disposed of by the Trustee in
accordance with its customary procedures, unless by Company Order the Company
shall direct that cancelled Securities be returned to it.

          SECTION 312.  COMPUTATION OF INTEREST.

          Except as otherwise specified as contemplated by Section 301 with
respect to any Securities, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

          SECTION 313.  CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF
SECURITIES.

          (a)  With respect to Registered Securities of any series not
permitting the election provided for in paragraph (b) below or the Holders of
which have not made the election provided for in paragraph (b) below, and with
respect to Bearer Securities of any series, except as provided in paragraph (d)
below, payment of the principal of (and premium, if any) and interest, if any,
on any Registered or Bearer Security of such series will be made in the Currency
in which such Registered Security or Bearer Security, as the case may be, is 

<PAGE>
                                          54


payable.  The provisions of this Section 313 may be modified or superseded with
respect to any Securities pursuant to Section 301.

          (b)  It may be provided pursuant to Section 301 with respect to
Registered Securities of any series that Holders shall have the option, subject
to paragraphs (d) and (e) below, to receive payments of principal of (or
premium, if any) or interest, if any, on such Registered Securities in any of
the Currencies which may be designated for such election by delivering to the
Trustee a written election with signature guarantees and in the applicable form
established pursuant to Section 301, not later than the close of business on the
Election Date immediately preceding the applicable payment date.  If a Holder so
elects to receive such payments in any such Currency, such election will remain
in effect for such Holder or any transferee of such Holder until changed by such
Holder or such transferee by written notice to the Trustee (but any such change
must be made not later than the close of business on the Election Date
immediately preceding the next payment date to be effective for the payment to
be made on such payment date and no such change of election may be made with
respect to payments to be made on any Registered Security of such series with
respect to which an Event of Default has occurred or with respect to which the
Company has deposited funds pursuant to Article Four or Fourteen or with respect
to which a notice of redemption has been given by the Company or a notice of
option to elect repayment has been sent by such Holder or such transferee).  Any
Holder of any such Registered Security who shall not have delivered any such
election to the Trustee not later than the close of business on the applicable
Election Date will be paid the amount due on the applicable payment date in the
relevant Currency as provided in Section 313(a).  The Trustee shall notify the
Exchange Rate Agent as soon as practicable after the Election Date of the
aggregate principal amount of Registered Securities for which Holders have made
such written election.

          (c)  Unless otherwise specified pursuant to Section 301, if the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301, then, unless otherwise specified pursuant to Section 301, not later
than the fourth Business Day after the Election Date for each payment date for
Registered Securities of any series, the Exchange Rate Agent will deliver to the
Company a written notice specifying, in the Currency in which Registered
Securities of such series are payable, the respective aggregate amounts of
principal of (and premium, if any) and interest, if any, on the Registered
Securities to be paid on such payment date, specifying the amounts in such
Currency so payable in respect of the Registered Securities as to which the
Holders of Registered Securities of such series shall have elected to be paid in
another Currency as provided in paragraph (b) above.  If the election referred
to in paragraph (b) above has been provided for pursuant to Section 301 and if
at least one Holder has made such election, then, unless otherwise specified
pursuant to Section 301, on the second Business Day preceding such payment date
the Company will deliver to the Trustee for such series of Registered Securities
an Exchange Rate Officers' Certificate in respect of the Dollar or Foreign
Currency payments to be made on such payment date.  Unless otherwise specified
pursuant to 

<PAGE>
                                          55


Section 301, the Dollar or Foreign Currency amount receivable by Holders of
Registered Securities who have elected payment in a Currency as provided in
paragraph (b) above shall be determined by the Company on the basis of the
applicable Market Exchange Rate in effect on the third Business Day (the
"Valuation Date") immediately preceding each payment date, and such
determination shall be conclusive and binding for all purposes, absent manifest
error.

          (d)  If a Conversion Event occurs with respect to a Foreign Currency
in which any of the Securities are denominated or payable other than pursuant to
an election provided for pursuant to paragraph (b) above or pursuant to the
terms of Section 301, then with respect to each date for the payment of
principal of (and premium, if any) and interest, if any, on the applicable
Securities denominated or payable in such Foreign Currency occurring after the
last date on which such Foreign Currency was used (the "Conversion Date"), the
Dollar shall be the Currency of payment for use on each such payment date. 
Unless otherwise specified pursuant to Section 301, the Dollar amount to be paid
by the Company to the Trustee and by the Trustee or any Paying Agent to the
Holders of such Securities with respect to such payment date shall be, in the
case of a Foreign Currency other than a currency unit, the Dollar Equivalent of
the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent
of the Currency Unit, in each case as determined by the Exchange Rate Agent in
the manner provided in paragraph (f) or (g) below.

          (e)  Unless otherwise specified pursuant to Section 301, if the Holder
of a Registered Security denominated in any Currency shall have elected to be
paid in another Currency as provided in paragraph (b) above, and a Conversion
Event occurs with respect to such elected Currency, such Holder shall receive
payment in the Currency in which payment would have been made in the absence of
such election; and if a Conversion Event occurs with respect to the Currency in
which payment would have been made in the absence of such election, such Holder
shall receive payment in Dollars as provided in paragraph (d) above or as
otherwise provided pursuant to Section 301.

          (f)  The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by converting the specified Foreign Currency into Dollars at the
Market Exchange Rate on the Conversion Date.

          (g)  The "Dollar Equivalent of the Currency Unit" shall be determined
as specified pursuant to Section 301.  "Election Date" shall mean the date for
any series of Registered Securities as specified pursuant to clause (11) of
Section 301 by which the written election referred to in paragraph (b) above may
be made.

          All decisions and determinations of the Exchange Rate Agent regarding
the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the
Currency Unit, the 

<PAGE>
                                          56


Market Exchange Rate and changes in the Specified Amounts as specified above
shall be in its sole discretion and shall, in the absence of manifest error, be
conclusive for all purposes and irrevocably binding upon the Company, the
Trustee and all Holders of such Securities denominated or payable in the
relevant Currency.  The Exchange Rate Agent shall promptly give written notice
to the Company and the Trustee of any such decision or determination.

          Except as otherwise provided pursuant to Section 301, in the event
that the Company determines in good faith that a Conversion Event has occurred
with respect to a Foreign Currency, the Company will immediately give written
notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee
will promptly thereafter give notice in the manner provided for in Section 106
to the affected Holders) specifying the Conversion Date.  Except as otherwise
provided pursuant to Section 301, in the event the Company so determines that a
Conversion Event has occurred with respect to any currency unit in which
Securities are denominated or payable, the Company will immediately give written
notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee
will promptly thereafter give notice in the manner provided for in Section 106
to the affected Holders) specifying the Conversion Date and the Specified Amount
of each Component Currency on the Conversion Date.  In the event the Company
determines in good faith that any subsequent change in any Component Currency as
set forth in the definition of Specified Amount above has occurred, the Company
will similarly give written notice to the Trustee and the Exchange Rate Agent.

          The Trustee shall be fully justified and protected in relying and
acting upon information received by it from the Company and the Exchange Rate
Agent and shall not otherwise have any duty or obligation to determine the
accuracy or validity of such information independent of the Company or the
Exchange Rate Agent.

          SECTION 314.  APPOINTMENT AND RESIGNATION OF SUCCESSOR EXCHANGE RATE
AGENT.

          (a)  Unless otherwise specified pursuant to Section 301, if and so
long as the Securities of any series (i) are denominated in a Currency other
than Dollars or (ii) may be payable in a Currency other than Dollars, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one Exchange Rate Agent.  The Company will cause the Exchange Rate
Agent to make the necessary foreign exchange determinations at the time and in
the manner specified pursuant to Section 301 for the purpose of determining the
applicable rate of exchange and, if applicable, for the purpose of converting
the issued Currency into the applicable payment Currency for the payment of
principal (and premium, if any) and interest, if any, pursuant to Section 313.

<PAGE>
                                          57


          (b)  No resignation of the Exchange Rate Agent and no appointment of a
successor Exchange Rate Agent pursuant to this Section shall become effective
until the acceptance of appointment by the successor Exchange Rate Agent as
evidenced by a written instrument delivered to the Company and the Trustee.

          (c)  If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agent for any cause with respect to the Securities of one or more series,
the Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 301, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are initially denominated and/or payable
in the same Currency).

          SECTION 315.  CUSIP NUMBERS.

          The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers, and, if so, the Trustee shall
use such "CUSIP" numbers in addition to serial numbers in notices of repurchase
as a convenience to Holders; PROVIDED that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a repurchase and that
reliance may be placed only on the serial or other identification numbers
printed on the Securities, and any such repurchase shall not be affected by any
defect in or omission of such "CUSIP" numbers.  The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

                              SATISFACTION AND DISCHARGE

          SECTION 401.  SATISFACTION AND DISCHARGE OF INDENTURE.

          This Indenture shall, upon Company Request, cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as to any surviving rights of registration of transfer or
exchange of Securities of such series expressly provided for herein or pursuant
hereto) and the Trustee, on demand of and at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series when

     (1)  either

               (A)  all Securities of such series theretofore authenticated and
          delivered and all coupons, if any, appertaining thereto (other than
          (i) coupons appertaining to Bearer Securities surrendered for exchange
          for Registered Securities and maturing after such exchange, whose
          surrender is not required or has been waived as provided in Section
          306, (ii) Securities and coupons of such series which have been
          destroyed, lost or stolen and which have been replaced or paid as
          provided in Section 307, (iii) coupons appertaining to Securities
          called for redemption and maturing after the relevant Redemption Date,
          whose surrender has been waived as provided in Section 1106, and (iv)
          Securities and coupons of such series for whose payment money has
          theretofore been deposited in trust with the Trustee or any Paying
          Agent or segregated and held in trust by the Company and thereafter
          repaid to the Company, as provided in Section 1003) have been
          delivered to the Trustee for cancellation; or

               (B)  all Securities of such series and, in the case of (i) or
          (ii) below, any coupons appertaining thereto not theretofore delivered
          to the Trustee for cancellation

                    (i)  have become due and payable, or

                    (ii) will become due and payable at their Stated Maturity
               within one year, or

                    (iii)  if redeemable at the option of the Company, are to be
               called for redemption within one year under arrangements
               satisfactory to the Trustee for the giving of notice of
               redemption by the Trustee in the name, and at the expense, of the
               Company,

          and the Company, in the case of (i), (ii) or (iii) above, has
          irrevocably deposited or caused to be deposited with the Trustee as
          trust funds in trust for such purpose an amount in the Currency in
          which the Securities of such series are payable, sufficient to pay and
          discharge the entire indebtedness on such Securities not theretofore
          delivered to the Trustee for cancellation, for principal (and premium,
          if any) and interest, if any, to the date of such deposit (in the case
          of Securities which have become due and payable) or to the Stated
          Maturity or Redemption Date, as the case may be;

                                          59

          (2)  the Company has paid or caused to be paid all other sums payable
     hereunder by the Company; and

          (3)  the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture as to such series have been complied with.

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606, the obligations of
the Trustee to any Authenticating Agent under Section 612 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Subsection (1)
of this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

          SECTION 402.  APPLICATION OF TRUST MONEY.

          Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest, if any, for whose payment such money has been
deposited with the Trustee.

                                       REMEDIES

          SECTION 501.  EVENTS OF DEFAULT.

          "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events:

          (1)  default in the payment of any interest on any Security of that
     series, or any related coupon, when such interest or coupon becomes due and
     payable, and continuance of such default for a period of 30 days; or

          (2)  default in the payment of the principal of (or premium, if any,
     on) any Security of that series at its Maturity, upon acceleration,
     redemption or otherwise; or

          (3)  default in the deposit of any sinking fund payment, when and as
     due by the terms of the Securities of that series and Article Twelve; or 

<PAGE>

                                          60


          (4)  the Company fails to comply with any of its other agreements or
     covenants in, or provisions applicable to, the Securities of that series or
     this Indenture, and the Default continues for the period and after the
     notice, if any, specified below; or 

          (5)  a default occurs under any mortgage, indenture or instrument
     under which there may be issued or by which there may be secured or
     evidenced any Indebtedness for money borrowed by the Company or one of its
     Restricted Subsidiaries (or the payment of which is guaranteed by the
     Company or one of its Restricted Subsidiaries), whether such Indebtedness
     or guarantee now exists or shall be created hereafter (but excluding any
     Indebtedness for the deferred purchase price of property or services owed
     to the Person providing such property or services as to which the Company
     or such Restricted Subsidiary is contesting its obligation to pay the same
     in good faith and by proper proceedings and for which the Company or such
     Restricted Subsidiary has established appropriate reserves), and (i) either
     (A) such event of default results from the failure to pay any such
     Indebtedness at final maturity or (B) as a result of such event of default
     the maturity of such Indebtedness has been accelerated prior to its
     expressed maturity and (ii) the principal amount of such Indebtedness
     equals $10,000,000 or more or, together with the principal amount of any
     such Indebtedness in default for failure to pay principal at maturity or
     the maturity of which has been so accelerated, aggregates $10,000,000 or
     more; or

          (6)  a final judgment or final judgments for the payment of money are
     entered by a court or courts of competent jurisdiction against the Company
     or any Restricted Subsidiary and either (i) an enforcement proceeding shall
     have been commenced by any creditor upon such judgment or (ii) such
     judgment remains undischarged and unbonded for a period (during which
     execution shall not be effectively stayed) of 60 days, PROVIDED that the
     aggregate of all such judgments exceeds $10,000,000; or

          (7)  the Company pursuant to or within the meaning of any Bankruptcy
     Law:

               (i)  commences a voluntary case or proceeding, 

               (ii)  consents to the entry of an order for relief against it in
          an involuntary case or proceeding,

               (iii)  consents to the appointment of a Custodian of it or for
          all or substantially all of its property,

               (iv)  makes a general assignment for the benefit of its
     creditors, or

<PAGE>
                                          61


               (v)  admits in writing that it generally is unable to pay its
          debts as the same become due; or

          (8)  a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (i)  is for relief against the Company in an involuntary case or
          proceeding,

               (ii)  appoints a Custodian of the Company or for all or
          substantially all of its property, or

               (iii)  orders the liquidation of the Company;

     and in each case the order or decree remains unstayed and in effect for 60
     days; or

          (9)  any other Event of Default provided with respect to Securities of
     that series.

          A Default under Section 501(4) is not an Event of Default with respect
to a series until the Trustee notifies the Company in writing, or the Holders of
at least 25% in principal amount of all Outstanding Securities of such series
notify the Company and the Trustee in writing, of the Default, and the Company
does not cure the Default within 60 days (30 days in the case of a Default under
Section 801 or 1004) after receipt of the notice.  The notice must specify the
Default, demand that it be remedied and state that the notice is a "Notice of
Default."  Such notice to the Company shall be given by the Trustee if so
requested in writing by the Holders of 25% of the principal amount of all the
Outstanding Securities of such series.

          SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

          If an Event of Default (other than an Event of Default specified in
Section 501(7) or 501(8)) with respect to the Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of at least 25% in principal amount of the Outstanding Securities
of such series, by written notice to the Company  (and to the Trustee if such
notice is given by such Holders), may, and the Trustee at the written request of
such Holders shall, declare all unpaid principal of (or, if the Securities of
such series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of that
series), premium, if any, and accrued interest on all the Outstanding Securities
of such series to be due and payable, as specified below.  Upon a declaration of
acceleration with respect to Securities of any series (or of all series, as the
case may be), such principal and accrued interest shall be 


<PAGE>
                                          62


due and payable upon the first to occur of an acceleration under the Bank Credit
Agreement or 10 days after receipt by the Company of such written notice given
hereunder.  If an Event of Default specified in Section 501(7) or 501(8) with
respect to the Company occurs, the amounts described above with respect to the
Outstanding Securities of all series shall IPSO FACTO become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holder.  Upon payment of such principal and interest, all of the
Company's obligations under the Securities of such Series and this Indenture,
other than obligations under Section 606, shall terminate.  

          The Holders of at least a majority in principal amount of the
Outstanding Securities of any series (or of all series, as the case may be), by
written notice to the Trustee, may rescind an acceleration and its consequences
if (i) all existing Events of Default, other than the non-payment of principal
of, premium, if any, or interest on the Outstanding Securities of such series
(or of all series, as the case may be) and any related coupons which have become
due solely because of the acceleration, have been cured or waived and (ii) the
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

          Notwithstanding the preceding paragraph, in the event of a declaration
of acceleration in respect of the Securities of any series because an Event of
Default specified in Section 501(5) shall have occurred and be continuing, such
declaration of acceleration shall be automatically annulled if the Indebtedness
that is the subject of such Event of Default has been discharged or the holders
thereof have rescinded their declaration of acceleration in respect of such
Indebtedness, and written notice of such discharge or rescission, as the case
may be, shall have been given to the Trustee by the Company and countersigned by
the holders of such Indebtedness or a trustee, fiduciary or agent for such
holders, within 30 days after such declaration of acceleration in respect of the
Securities of such series, and no other Event of Default has occurred during
such 30-day period which has not been cured or waived during such period.

          SECTION 503.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

          The Company covenants that if

          (1)  default is made in the payment of any interest on any Security
     and any related coupon when such interest becomes due and payable and such
     default continues for a period of 30 days, or

          (2)  default is made in the payment of the principal of (or premium,
     if any, on) any Security at the Maturity thereof,

then the Company will, upon demand of the Trustee, pay to it for the benefit of
the Holders of such Securities and coupons, the whole amount then due and
payable on such Securities and coupons for principal (and premium, if any) and
interest, if any, and interest on any overdue principal (and premium, if any)
and on any overdue interest, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

          If an Event of Default with respect to Securities of any series (or of
all series, as the case may be) occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series (or of all series, as the case may be)
under this Indenture by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce such rights.

          SECTION 504.  TRUSTEE MAY FILE PROOFS OF CLAIM.

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any 

<PAGE>
                                          64


demand on the Company for the payment of overdue principal, premium, if any, or
interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

          (i)  to file and prove a claim for the whole amount of principal (and
     premium, if any), or such portion of the principal amount of any series of
     Original Issue Discount Securities or Indexed Securities as may be
     specified in the terms of such series, and interest, if any, owing and
     unpaid in respect of the Securities and to file such other papers or
     documents as may be necessary or advisable in order to have the claims of
     the Trustee (including any claim for the reasonable compensation, expenses,
     disbursements and advances of the Trustee, its agents and counsel) and of
     the Holders allowed in such judicial proceeding, and

          (ii) to collect and receive any moneys or other property payable or
     deliverable on any such claims and to distribute the same; and any
     custodian, receiver, assignee, trustee, liquidator, sequestrator or other
     similar official in any such judicial proceeding is hereby authorized by
     each Holder to make such payments to the Trustee and, in the event that the
     Trustee shall consent to the making of such payments directly to the
     Holders, to pay to the Trustee any amount due it for the reasonable
     compensation, expenses, disbursements and advances of the Trustee, its
     agents and counsel, and any other amounts due the Trustee under Section
     606.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any proposal,
plan of reorganization, arrangement, adjustment or composition or other similar
arrangement affecting the Securities or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

          SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES.

          All rights of action and claims under this Indenture or the Securities
or coupons may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or coupons or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name and as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.

          SECTION 506.  APPLICATION OF MONEY COLLECTED.

          Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, if any, upon presentation of the Securities or coupons, or
both, as the case may be, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee under Section
     606;

          SECOND:  To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest, if any, on the Securities
     and coupons in respect of which or for the benefit of which such money has
     been collected, ratably, without preference or priority of any kind,
     according to the amounts due and payable on such Securities and coupons for
     principal (and premium, if any) and interest, if any, respectively; and

          THIRD:  The balance, if any, to the Company.

          SECTION 507.  LIMITATION ON SUITS.

          No Holder of any Security of any series or any related coupons shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless 

          (1)  such Holder has previously given written notice to the Trustee of
     a continuing Event of Default with respect to the Securities of that
     series;

          (2)  the Holders of not less than 25% in principal amount of the
     Outstanding Securities of that series in the case of any Event of Default
     described in clause (1), (2), (3), (4), (5), (6) or (9) of Section 501, or,
     in the case of any Event of Default described in clause (7) or (8) of
     Section 501, the Holders of not less than 25% in principal amount of all
     Outstanding Securities, shall have made written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

          (3)  such Holder or Holders have offered to the Trustee reasonable
     indemnity against the costs, expenses and liabilities to be incurred in
     compliance with such request;

          (4)  the Trustee for 60 days after its receipt of such notice, request
     and offer of indemnity has failed to institute any such proceeding; and

<PAGE>
                                          66


          (5)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     or more in principal amount of the Outstanding Securities of that series in
     the case of any Event of Default described in clause (1), (2), (3), (4),
     (5), (6) or (9) of Section 501, or, in the case of any Event of Default
     described in clause (7) or (8) of Section 501, by the Holders of a majority
     or more in principal amount of all Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Securities of the same series, in the case of any Event of Default
described in clause (1), (2), (3), (4), (5), (6) or (9) of Section 501, or of
Holders of all Securities in the case of any Event of Default described in
clause (7) or (8) of Section 501, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all Holders of Securities of the same series, in the case of any
Event of Default described in clause (1), (2), (3), (4), (5), (6) or (9) of
Section 501, or of Holders of all Securities in the case of any Event of Default
described in clause (7) or (8) of Section 501.

          SECTION 508.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM AND INTEREST.

          Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 308) interest, if any, on, such Security or payment of such coupon on
the respective Stated Maturities expressed in such Security or coupon (or, in
the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

          SECTION 509.  RESTORATION OF RIGHTS AND REMEDIES.

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case the Company, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                          67


          SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.

          Except as otherwise provided in Section 307, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or
coupons is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          SECTION 511.  DELAY OR OMISSION NOT WAIVER.

          No delay or omission of the Trustee or of any Holder of any Security
or coupon to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

          SECTION 512.  CONTROL BY HOLDERS.

          With respect to the Securities of any series, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such series
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee, PROVIDED that in each case

          (1)  such direction shall not be in conflict with any rule of law or
     with this Indenture or expose the Trustee to personal liability, and

          (2)  subject to the provisions of the TIA Section 315, the Trustee may
     take any other action deemed proper by the Trustee which is not
     inconsistent with such direction.

          SECTION 513.  WAIVER OF PAST DEFAULTS.

          Subject to Section 502, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past Default or Event
of Default described in clause (1), (2), (3), (4), (5), (6) or (9) of Section
501 (or, in the case of a Default or Event of Default  described in clause (7)
or (8) of Section 501, the Holders of not less than a majority in 

<PAGE>
                                          68


principal amount of all Outstanding Securities may waive any such past Default
or Event of Default), and its consequences, except a Default or Event of
Default.

          (1)  in respect of the payment of the principal of (or premium, if
     any) or interest, if any, on any Security or any related coupon, or

          (2)  in respect of a covenant or provision hereof which under Article
     Nine cannot be modified or amended without the consent of the Holder of
     each Outstanding Security of such series affected.

          Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

          SECTION 514.  UNDERTAKING FOR COSTS.

          All parties to this Indenture agree, and each Holder of Securities of
any series by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on Securities of any series on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date); PROVIDED that neither this Section 514 nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company.

          SECTION 515.  WAIVER OF STAY OR EXTENSION LAWS.

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the 

<PAGE>
                                          69


execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.


                                     ARTICLE SIX

                                     THE TRUSTEE

          SECTION 601.  NOTICE OF DEFAULTS.

          Within 90 days after the occurrence of any Default hereunder with
respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders, as their names and addresses appear in the Security Register,
notice of such default hereunder known to the Trustee, unless such Default shall
have been cured or waived; PROVIDED, HOWEVER, that, except in the case of a
default in the payment of the principal of (or premium, if any) or interest, if
any, on any Security of such series or in the payment of any sinking fund
installment with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders of Securities of such series and any
related coupons; and PROVIDED FURTHER that in the case of any default or breach
of the character specified in Section 501(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof.

          SECTION 602.  CERTAIN RIGHTS OF TRUSTEE.

          Subject to the provisions of TIA Sections 315(a) through 315(d):

     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein 

<PAGE>
                                          70


     specifically prescribed) may, in the absence of bad faith on its part, rely

     document, but the Trustee, in its discretion, may make such further inquiry
     or investigation into such facts or matters as it may see fit, and, if the

     shall be entitled to examine the books, records and premises of the
     Company, personally or by agent or attorney;

          (7)  the Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; and

          (8)  no provision of this Indenture shall require the Trustee to

<PAGE>
                                          71


of this Indenture or of the Securities or coupons.  The Trustee shall not be

its obligations hereunder and that the statements to be made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein.  Neither the Trustee

          (1)  to pay to the Trustee from time to time such compensation as

     express trust);

          (2)  except as otherwise expressly provided herein, to reimburse the
     Trustee upon its request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustee in accordance with any provision

     to hold it harmless against, any and all loss, damage, claim, liability or
     expense including taxes (other than taxes based on the income of the
     Trustee) incurred without negligence or bad faith on its part, arising out
     of or in connection with the acceptance or administration of this trust,
     including the costs and expenses of defending itself against any claim or
     liability in connection with the exercise or performance of any of its
     powers or duties hereunder.

under this Section 606, the Trustee shall have a lien prior to the Securities
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of principal of (or premium, if any) or
interest, if any, on particular Securities or any coupons.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(5) or (6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services will be intended to constitute expenses of
administration under any Bankruptcy Law.

Indenture.

surplus of at least $50,000,000.  If such Trustee publishes reports of condition
at least annually, pursuant to law or to the requirements of Federal, State,
Territorial or District of Columbia supervising or examining authority, then for
the purposes of this Section 608, the combined capital and surplus of the
Trustee shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published.  If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
608, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 610.

of one or more series by giving written notice thereof to the Company.  If the
instrument of acceptance by a successor Trustee required by Section 609 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.


          (c)  The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of removal, the removed Trustee may petition a court of competent
jurisdiction for the appointment of a successor Trustee.

          (d)  If at any time:

          (1)  the Trustee shall fail to comply with the provisions of TIA
     Section 310(b) after written request therefor by the Company or by any
     Holder who has been a bona fide Holder of a Security for at least six
     months, or 

          (2)  the Trustee shall cease to be eligible under Section 608 and
     shall fail to resign after written request therefor by the Company or by
     any Holder who has been a bona fide Holder of a Security for at least six
     months, or 

          (3)  the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee with respect to all Securities, or (ii) subject to TIA Section 514, the
Holder of any Security who has been a bona fide Holder of a Security for at
least six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the removal of the Trustee with
respect to all Securities and the appointment of a successor Trustee or
Trustees.

          (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series).  If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with Section 610, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company.  If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

          (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to the Holders of Securities of such series in the manner provided for in
Section 106.  Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

          SECTION 610.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

          (a)  Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; PROVIDED, HOWEVER, that the
retiring Trustee shall continue to be entitled to the benefit of Section 606;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

<PAGE>
                                          75


          (b)  In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.  Whenever there is a successor Trustee with
respect to one or more (but less than all) series of securities issued pursuant
to this Indenture, the terms "Indenture" and "Securities" shall have the
meanings specified in the provisos to the respective definitions of those terms
in Section 101 which contemplate such situation.

          (c)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

          (d)  No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

          SECTION 611.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. 
In case any of the Securities shall not have been authenticated by such
predecessor Trustee, any successor Trustee may authenticate such Securities
either in the name of any predecessor hereunder or in the name of the successor
Trustee.  In all such cases such certificates shall have the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee; PROVIDED, HOWEVER, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Securities in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

          SECTION 612.  APPOINTMENT OF AUTHENTICATING AGENT.

          At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series and the Trustee shall give written notice
of such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106.  Securities so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Any such appointment shall be evidenced
by an instrument in writing signed by a Responsible Officer of the Trustee, and
a copy of such instrument shall be promptly furnished to the Company.  Wherever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee's certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent.  Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any state thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by 

<PAGE>
                                          77


federal or state authority.  If such corporation publishes reports of condition
at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect specified in this Section.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, PROVIDED such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give written notice of
such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106.  Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

          The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

          If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:

     Dated:  ____________________

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

          With the consent of the Holders of not less than a majority in

the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.  Any such
supplemental indenture adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture, or modifying in any manner
the rights of the Holders of Securities of such series, shall not affect the
rights under this Indenture of the Holders of Securities of any other series.

          It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

          In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to TIA Section 315(a) through 315(d) and Section 602 hereof) shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture.  The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

          SECTION 904.  EFFECT OF SUPPLEMENTAL INDENTURES.

          Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental

of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture.  If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

          SECTION 907.  NOTICE OF SUPPLEMENTAL INDENTURES.

          Promptly after the execution by the Company and the Trustee of any

in the manner provided for in Section 106, setting forth in general terms the
substance of such supplemental indenture.

          SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST.

          The Company covenants and agrees for the benefit of the Holders of
each series of Securities and any related coupons that it will duly and
punctually pay the principal of (and premium, if any) and interest, if any, on
the Securities of that series in accordance with the terms of the Securities,
any coupons appertaining thereto and this Indenture.  Unless otherwise specified
as contemplated by Section 301 with respect to any series of Securities, any
interest installments due on Bearer Securities on or before Maturity shall be
payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature.

          SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

          If the Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series that
are convertible or exchangeable may be surrendered for conversion or exchange,
as applicable and where notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be served.

          If Securities of a series are issuable as Bearer Securities, the
Company will maintain (A) in The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where Securities of that series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable, where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served and where Bearer Securities of that series and
related coupons may be presented or surrendered for payment in the circumstances
described in the following paragraph (and not otherwise) (B) subject to any laws
or regulations applicable thereto, in a Place of Payment for that series which
is located outside the United States, an office or agency where Securities of
that series and related coupons may be presented and surrendered for payment;
PROVIDED, HOWEVER, that, if the Securities of that series are listed on any
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in any required city located outside the United States so long as the
Securities of that series are listed on such exchange, and (C) subject to any
laws or regulations applicable thereto, in a Place of 

<PAGE>
                                          86


Payment for that series located outside the United States an office or agency
where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where Securities of that series that are convertible and exchangeable
may be surrendered for conversion or exchange, as applicable and where notices
and demands to or upon the Company in respect of the Securities of that series
and this Indenture may be served.


          The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency.  If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of any series and the
related coupons may be presented and surrendered for payment at the offices
specified in the Security, in London, and the Company hereby appoints the same
as its agents to receive such respective presentations, surrenders, notices and
demands.

          Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; PROVIDED, HOWEVER, that, if
the Securities of a series are payable in Dollars, payment of principal of (and
premium, if any) and interest, if any, on any Bearer Security shall be made at
the office of the Company's Paying Agent in The City of New York, if (but only
if) payment in Dollars of the full amount of such principal, premium or
interest, as the case may be, at all offices or agencies outside the United
States maintained for such purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
any such designation; PROVIDED, HOWEVER, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes.  The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.  Unless otherwise specified with
respect to any Securities as contemplated by Section 301 with respect to a
series of Securities, the Company hereby designates as a Place of Payment for
each series of Securities the office or agency of the Company in the Borough of
Manhattan, The City of New York, and initially appoints the Trustee at its
Corporate Trust Office as Paying Agent in such city and as its agent to receive
all such presentations, surrenders, notices and demands.

          Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Currency other than Dollars or (ii) may be payable in a Currency other than
Dollars, or so long as it is required under any other provision of the
Indenture, then the Company will maintain with respect to each such series of
Securities, or as so required, at least one Exchange Rate Agent.

          SECTION 1003.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

          If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities and any related coupons, it will, on or
before each due date of the principal of (or premium, if any) or interest, if
any, on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay the principal
of (or premium, if any) or interest, if any, on Securities of such series so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

          Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, prior to or on each due
date of the principal of (or premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent a sum (in the Currency
described in the preceding paragraph) sufficient to pay the principal (or
premium, if any) or interest, if any, so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

          The Company will cause each Paying Agent (other than the Trustee) for
any series of Securities to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

          (1)  hold all sums held by it for the payment of the principal of (and
     premium, if any) and interest, if any, on Securities of such series in
     trust for the benefit of the Persons entitled thereto until such sums shall
     be paid to such Persons or otherwise disposed of as herein provided;

          (2)  give the Trustee notice of any default by the Company (or any
     other obligor upon the Securities of such series) in the making of any
     payment of principal of (or premium, if any) or interest, if any, on the
     Securities of such series; and

<PAGE>
                                          88


          (3)  at any time during the continuance of any such default, upon the
     written request of the Trustee, forthwith pay to the Trustee all sums so
     held in trust by such Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

          Except as provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (or premium, if any) or interest, if
any, on any Security of any series, or any coupon appertaining thereto, and
remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security or coupon shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

          SECTION 1004.  CORPORATE EXISTENCE.

          Subject to Article Eight, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of each Restricted Subsidiary and the corporate rights
(charter and statutory), corporate licenses and corporate franchises of the
Company and its Restricted Subsidiaries, except where a failure to do so, singly
or in the aggregate, is not likely to have a materially adverse effect upon the
business, assets, financial condition or results of operations of the Company
and the Restricted Subsidiaries taken as a whole determined on a consolidated
basis in accordance with generally accepted accounting principles; PROVIDED that
the Company shall not be required to preserve any such existence (except of the
Company), right, license or franchise if the Board of Directors, or of the
Restricted Subsidiary concerned, shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company or 

<PAGE>
                                          89


such Restricted Subsidiary and that the loss thereof is not disadvantageous in
any material respect to the Holders.

          SECTION 1005.  PAYMENT OF TAXES AND OTHER CLAIMS.

          The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all material taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the
income, profits or property of the Company or any of its Subsidiaries and (b)
all material lawful claims for labor, materials and supplies, which, if unpaid,
might by law become a lien upon the property of the Company or any Restricted
Subsidiary; PROVIDED, HOWEVER, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings.

          SECTION 1006.  MAINTENANCE OF PROPERTIES.

          The Company shall cause all material properties owned by or leased to
it or any Restricted Subsidiary and necessary in the conduct of its business or
the business of such Restricted Subsidiary to be maintained and kept in normal
condition, repair and working order, ordinary wear and tear excepted; PROVIDED
that nothing in this Section shall prevent the Company or any Restricted
Subsidiary from discontinuing the use, operation or maintenance of any of such
properties, or disposing of any of them, if such discontinuance or disposal is,
in the judgment of the Board of Directors or the Restricted Subsidiary
concerned, or of any officer (or other agent employed by the Company or any
Restricted Subsidiary) of the Company or such Restricted Subsidiary having
managerial responsibility for any such property, desirable in the conduct of the
business of the Company or any Restricted Subsidiary of the Company and if such
discontinuance or disposal is not adverse in any material respect to the
Holders.

          The Company shall provide or cause to be provided, for itself and any
Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations
similarly situated and owning like properties in the same general areas in which
the Company or such Restricted Subsidiaries operate.

          SECTION 1007.  LIMITATION ON INDEBTEDNESS.

          The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, incur, create, issue, assume, guarantee or otherwise
become liable for, contingently or otherwise, or become responsible for the
payment of, contingently or otherwise, any Indebtedness (other than Indebtedness
between or among any of the Company 

<PAGE>
                                          90


and Restricted Subsidiaries) unless, after giving effect thereto, the Cash Flow
Ratio shall be less than or equal to 9 to 1.

          SECTION 1008.  LIMITATION ON LIENS.

          The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, create, incur, assume or suffer to exist any Lien of
any kind, except for Permitted Liens, on or with respect to any of its property
or assets, whether owned at the date of this Indenture or hereafter acquired, or
any income, profits or proceeds therefrom, or assign or otherwise convey any
right to receive income thereon, unless (x) in the case of any Lien securing
Indebtedness that is subordinated in right of payment to the Securities of any
series, the Securities of such series are secured by a Lien on such property,
assets or proceeds that is senior in priority to such Lien and (y) in the case
of any other Lien, the Securities of such series are equally and ratably
secured.

          SECTION 1009.  LIMITATION ON RESTRICTED PAYMENTS.

          Except as otherwise provided in this Section 1009, the Company shall
not, and shall not permit any Restricted Subsidiary to, make any Restricted
Payment if (a) at the time of such proposed Restricted Payment, a Default or
Event of Default shall have occurred and be continuing or shall occur as a
consequence of such Restricted Payment or (b) immediately after giving effect to
such Restricted Payment, the aggregate of all Restricted Payments that shall
have been made on or after July 1, 1988 would exceed the sum of:

          (i)  $25,000,000, plus

          (ii) an amount equal to the difference between (A) the Cumulative Cash
     Flow Credit and (B) 1.2 multiplied by Cumulative Interest Expense.

          For purposes of this Section 1009, the amount of any Restricted
Payment, if other than cash, shall be based upon fair market value as determined
by the Board of Directors, whose good faith determination shall be conclusive.

          The foregoing provisions of this Section 1009 shall not prevent (i)
the payment of any dividend within 60 days after the date of declaration
thereof, if at such date of declaration such payment complied with the
provisions of this Section 1009; (ii) the retirement, redemption, purchase,
defeasance or other acquisition of any shares of the Company's Capital Stock or
warrants, rights or options to acquire Capital Stock of the Company, in exchange
for, or out of the proceeds of a sale (within one year before or 180 days after
such retirement, redemption, purchase, defeasance or other acquisition) of,
other shares of its Capital Stock or warrants, rights or options to acquire
Capital Stock of the Company; and (iii) the redemption of, or payments of cash
dividends on, the Company's 8% 

<PAGE>
                                          91


Series C Cumulative Preferred Stock (the "Series C Preferred Stock") outstanding
on January 1, 1997, which redemptions or dividends are provided for by the terms
of the Series C Preferred Stock in effect on such date (or the redemption of or
payment of cash dividends on any security of the Company issued in exchange for
or upon the conversion of such Series C Preferred Stock; PROVIDED that the
aggregate amount payable pursuant to the terms of such security is no greater
than the aggregate amount payable pursuant to the terms of the Series C
Preferred Stock).  For purposes of determining the aggregate permissible amount
of Restricted Payments in accordance with clause (b) of the first paragraph of
this Section 1009, all amounts expended pursuant to clauses (i) and (iii) of
this paragraph shall be included and all amounts expended or received pursuant
to clause (ii) of this paragraph shall be excluded; PROVIDED, HOWEVER, that
amounts paid pursuant to clause (i) of this paragraph shall be included only to
the extent that such amounts were not previously included in calculating
Restricted Payments.

          For the purposes of this Section 1009, the net proceeds from the 
issuance of shares of Capital Stock of the Company upon conversion of 
Indebtedness shall be deemed to be an amount equal to (i) the accreted value 
of such Indebtedness on the date of such conversion and (ii) the additional 
consideration, if any, received by the Company upon such conversion thereof, 
less any cash payment on account of fractional shares (such consideration, if 
in property other than cash, to be determined by the Board of Directors, 
whose good faith determination shall be conclusive). If the Company makes a 
Restricted Payment which, at the time of the making of such Restricted 
Payment, would in the good faith determination of the Company be permitted 
under the requirements of this Section 1009, such Restricted Payment shall be 
deemed to have been made in compliance with this Section 1009 notwithstanding 
any subsequent adjustments made in good faith to the Company's financial 
statements affecting Cumulative Cash Flow Credit or Cumulative Interest 
Expense for any period.

          SECTION 1010.  LIMITATION ON INVESTMENTS IN UNRESTRICTED SUBSIDIARIES
AND AFFILIATES.

          The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, (i) make any Investment or (ii) allow any Restricted
Subsidiary to become an Unrestricted Subsidiary (a "redesignation of a
Restricted Subsidiary"), in each case unless (a) no Default or Event of Default
shall have occurred and be continuing or shall occur as a consequence of such
Investment or such redesignation of a Restricted Subsidiary and (b) after giving
effect thereto, the Cash Flow Ratio shall be less than or equal to 9 to 1.

          The foregoing provisions of this Section 1010 shall not prohibit (i)
any renewal or reclassification of any Investment existing on the date hereof or
(ii) trade credit extended on usual and customary terms in the ordinary course
of business.

          SECTION 1011.  TRANSACTIONS WITH AFFILIATES.

          The Company shall not, and shall not permit any of its Subsidiaries
to, sell, lease, transfer or otherwise dispose of any of its properties or
assets to or purchase any property or assets from, or enter into any contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, an Affiliate of the Company that is not a Subsidiary, having a value, or for
consideration having a value, in excess of $10,000,000 individually or in the
aggregate unless the Board of Directors shall make a good faith determination
that the terms of such transaction are, taken as a whole, no less favorable to
the Company or such subsidiary, as the case may be, than those which might be
available in a comparable transaction with an unrelated Person.  For purposes of
clarification, this Section 1011 shall not apply to any Restricted Payments
permitted by Section 1009.

          SECTION 1012.  PROVISION OF FINANCIAL STATEMENTS.

          (a)  The Company shall supply without cost to each Holder of the
Securities of any series, and file with the Trustee (if not otherwise filed with
the Trustee pursuant to Section 703) within 30 days after the Company is
required to file the same with the Commission, copies of the annual reports and
quarterly reports and of the information, documents and other reports which the
Company may be required to file with the Commission pursuant to Section 13(a),
13(c) or 15(d) of the Exchange Act.

          (b)  If the Company is not required to file with the Commission such
reports and other information referred to in Section 1012(a), the Company shall
furnish without cost to each Holder of the Securities and file with the Trustee
(i) within 140 days after the end of each fiscal year, annual reports containing
the information required to be contained in Items 1, 2, 3, 6, 7, 8 and 9 of Form
10-K promulgated under the Exchange Act, or substantially the same information
required to be contained in comparable items of any successor form, and (ii)
within 75 days after the end of each of the first three fiscal quarters of each
fiscal year, quarterly reports containing the information required to be
contained in Form 10-Q promulgated under the Exchange Act, or substantially the
same information required to be contained in any successor form.

          SECTION 1013.  STATEMENT AS TO COMPLIANCE.

          The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year ending after the date hereof, a brief certificate of its
principal executive officer, principal financial officer or principal accounting
officer stating whether, to such officer's knowledge, the Company is in
compliance with all covenants and conditions to be complied with by it under
this Indenture.  For purposes of this Section 1013, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

          SECTION 1014.  WAIVER OF CERTAIN COVENANTS.

          The Company may omit in any particular instance to comply with any
covenant or condition set forth in Sections 1007 through 1012 with respect to
Securities of any series if, before or after the time for such compliance, the
Holders of a majority in aggregate principal amount of all Outstanding
Securities of the series shall, by Act of such Holders, waive such compliance in
such instance or generally waive compliance with such covenant or condition, but
no such waiver shall extend to or affect such covenant or condition except to
the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any
such covenant or condition shall remain in full force and effect.

                               REDEMPTION OF SECURITIES

          SECTION 1101.  APPLICABILITY OF ARTICLE.

          Securities of any series which are redeemable before their Stated
Maturity shall be redeemable in accordance with the terms of such Securities and
(except as otherwise specified as contemplated by Section 301 for Securities of
any series) in accordance with this Article.

          SECTION 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

the election of the Company, the Company shall, at least 60 days prior to the
Redemption Date fixed by the Company (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such Redemption Date and of
the principal amount of Securities of such series to be redeemed and shall
deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Securities to be redeemed pursuant to Section 1103.  In
the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

          SECTION 1103.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

          If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal of Securities of such series; PROVIDED,
HOWEVER, that no such partial redemption shall reduce the portion of the
principal amount of a Security not redeemed to less than the minimum authorized
denomination for Securities of such series established pursuant to Section 301.

          The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

          SECTION 1104.  NOTICE OF REDEMPTION.

          Except as otherwise specified as contemplated by Section 301, notice
of redemption shall be given in the manner provided for in Section 106 not less
than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed.

          All notices of redemption shall identify the Securities (including
CUSIP number, if any) to be redeemed and shall state:

          (1)  the Redemption Date,

          (2)  the Redemption Price and the amount of accrued interest to the
     Redemption Date payable as provided in Section 1106, if any,

          (3)  if less than all the Outstanding Securities of any series are to
     be redeemed, the identification (and, in the case of partial redemption,
     the principal amounts) of the particular Securities to be redeemed,

          (4)  in case any Security is to be redeemed in part only, the notice
     which relates to such Security shall state that on and after the Redemption
     Date, upon surrender of such Security, the holder will receive, without
     charge, a new Security or 

<PAGE>
                                          95


     Securities of authorized denominations for the principal amount thereof
     remaining unredeemed,

          (5)  that on the Redemption Date, the Redemption Price and accrued
     interest, if any, to the Redemption Date payable as provided in Section
     1106 will become due and payable upon each such Security, or the portion
     thereof, to be redeemed and, if applicable, that interest thereon will
     cease to accrue on and after said date,

          (6)  the Place or Places of Payment where such Securities, together in
     the case of Bearer Securities with all coupons appertaining thereto, if
     any, maturing after the Redemption Date, are to be surrendered for payment
     of the Redemption Price and accrued interest, if any,

          (7)  that the redemption is for a sinking fund, if such is the case,

          (8)  that, unless otherwise specified in such notice, Bearer
     Securities of any series, if any, surrendered for redemption must be
     accompanied by all coupons maturing subsequent to the Redemption Date or
     the amount of any such missing coupon or coupons will be deducted from the
     Redemption Price unless security or indemnity satisfactory to the Company,
     the Trustee and any Paying Agent is furnished, and

          (9)  if Bearer Securities of any series are to be redeemed and any
     Registered Securities of such series are not to be redeemed, and if such
     Bearer Securities may be exchanged for Registered Securities not subject to
     redemption on such Redemption Date pursuant to Section 306 or otherwise,
     the last date, as determined by the Company, on which such exchanges may be
     made.

          Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

          SECTION 1105.  DEPOSIT OF REDEMPTION PRICE.

          Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money in the Currency in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
sufficient to pay the Redemption Price of, and accrued interest, if any, on, all
the Securities which are to be redeemed on that date.

                                          96


          SECTION 1106.  SECURITIES PAYABLE ON REDEMPTION DATE.

          Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified in the Currency in which the Securities of
such series are payable (except as otherwise specified pursuant to Section 301
for the Securities of such series and except, if applicable, as provided in
Sections 313(b), 313(d) and 313(e)) (together with accrued interest, if any, to
the Redemption Date), and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest, if any)
such Securities shall, if the same were interest-bearing, cease to bear interest
and the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void.  Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest, if any, to the Redemption Date; PROVIDED, HOWEVER, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and PROVIDED FURTHER
that installments of interest on Registered Securities whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 308.

          If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless.  If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; PROVIDED,
HOWEVER, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

          SECTION 1107.  SECURITIES REDEEMED IN PART.

          Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a Place
of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.


                                    ARTICLE TWELVE

                                    SINKING FUNDS

          SECTION 1201.  APPLICABILITY OF ARTICLE.

          Retirements of Securities of any series pursuant to any sinking fund
shall be made in accordance with the terms of such Securities and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

          The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1202.  Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

          SECTION 1202.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

          Subject to Section 1203, in lieu of making all or any part of any
mandatory sinking fund payment with respect to any Securities of a series in
cash, the Company may at its option (1) deliver to the Trustee Outstanding
Securities of a series (other than any previously called for redemption)
theretofore purchased or otherwise acquired by the Company together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and/or (2) receive credit for the principal amount of Securities of
such series which have been previously delivered to the Trustee by the Company
or for Securities of such series which have been redeemed either at the election
of the Company

<PAGE>
                                          98


pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any mandatory sinking fund payment
with respect to the Securities of the same series required to be made pursuant
to the terms of such Securities as provided for by the terms of such series;
PROVIDED, HOWEVER, that such Securities have not been previously so credited. 
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

          SECTION 1203.  REDEMPTION OF SECURITIES FOR SINKING FUND.

          Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) and the portion thereof, if any,
which is to be satisfied by delivering or crediting Securities of that series
pursuant to Section 1202 (which Securities will, if not previously delivered,
accompany such certificate) and whether the Company intends to exercise its
right to make a permitted optional sinking fund payment with respect to such
series.  Such certificate shall be irrevocable and upon its delivery the Company
shall be obligated to make the cash payment or payments therein referred to, if
any, on or before the next succeeding sinking fund payment date.  In the case of
the failure of the Company to deliver such certificate, the sinking fund payment
due on the next succeeding sinking fund payment date for that series shall be
paid entirely in cash and shall be sufficient to redeem the principal amount of
such Securities subject to a mandatory sinking fund payment without the option
to deliver or credit Securities as provided in Section 1202 and without the
right to make any optional sinking fund payment, if any, with respect to such
series.

          Not more than 60 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104.  Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

          Prior to any sinking fund payment date, the Company shall pay to the
Trustee or a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) in cash a sum equal to
any interest that will accrue 

<PAGE>
                                          99


to the date fixed for redemption of Securities or portions thereof to be
redeemed on such sinking fund payment date pursuant to this Section 1203.

          Notwithstanding the foregoing, with respect to a sinking fund for any
series of Securities, if at any time the amount of cash to be paid into such
sinking fund on the next succeeding sinking fund payment date, together with any
unused balance of any preceding sinking fund payment or payments for such
series, does not exceed in the aggregate $100,000, the Trustee, unless requested
by the Company, shall not give the next succeeding notice of the redemption of
Securities of such series through the operation of the sinking fund.  Any such
unused balance of moneys deposited in such sinking fund shall be added to the
sinking fund payment for such series to be made in cash on the next succeeding
sinking fund payment date or, at the written request of the Company, shall be
applied at any time or from time to time to the purchase of Securities of such
series, by public or private purchase, in the open market or otherwise, at a
purchase price for such Securities (excluding accrued interest and brokerage
commissions, for which the Trustee or any Paying Agent will be promptly
reimbursed by the Company) not in excess of the principal amount thereof.


                                   ARTICLE THIRTEEN

                            REPAYMENT AT OPTION OF HOLDERS

          SECTION 1301.  APPLICABILITY OF ARTICLE.

          Repayment of Securities of any series before their Stated Maturity at
the option of Holders thereof shall be made in accordance with the terms of such
Securities and (except as otherwise specified as contemplated by Section 301 for
Securities of any series) in accordance with this Article.

          SECTION 1302.  REPAYMENT OF SECURITIES.

          Securities of any series subject to repayment in whole or in part at
the option of the Holders thereof will, unless otherwise provided in the terms
of such Securities, be repaid at a price equal to the principal amount thereof,
together with interest, if any, thereon accrued to the Repayment Date specified
in or pursuant to the terms of such Securities.  The Company covenants that on
or before the Repayment Date it will deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money in the Currency in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay
the principal (or, if so provided by the terms of the Securities of any series,
a percentage of the principal) of and (except if the Repayment Date 

<PAGE>
                                         100


shall be an Interest Payment Date) accrued interest, if any, on, all the
Securities or portions thereof, as the case may be, to be repaid on such date.

          SECTION 1303.  EXERCISE OF OPTION.

          Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on the reverse
of such Securities.  To be repaid at the option of the Holder, any Security so
providing for such repayment, with the "Option to Elect Repayment" form on the
reverse of such Security duly completed by the Holder (or by the Holder's
attorney duly authorized in writing), must be received by the Company at the
Place of Payment therefor specified in the terms of such Security (or at such
other place or places of which the Company shall from time to time notify the
Holders of such Securities) not earlier than 45 days nor later than 30 days
prior to the Repayment Date.  If less than the entire principal amount of such
Security is to be repaid in accordance with the terms of such Security, the
principal amount of such Security to be repaid, in increments of the minimum
denomination for Securities of such series, and the denomination or
denominations of the Security or Securities to be issued to the Holder for the
portion of the principal amount of such Security surrendered that is not to be
repaid, must be specified.  The principal amount of any Security providing for
repayment at the option of the Holder thereof may not be repaid in part if,
following such repayment, the unpaid principal amount of such Security would be
less than the minimum authorized denomination of Securities of the series of
which such Security to be repaid is a part.  Except as otherwise may be provided
by the terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Company.

          SECTION 1304.  WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND
PAYABLE.

          If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void.  Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
PROVIDED, HOWEVER, that coupons whose Stated Maturity is on or prior to the
Repayment Date 

<PAGE>
                                         101


shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
pursuant to Section 301, only upon presentation and surrender of such coupons;
and PROVIDED FURTHER that, in the case of Registered Securities, installments of
interest, if any, whose Stated Maturity is on or prior to the Repayment Date
shall be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 308.

          If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; PROVIDED, HOWEVER, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

          If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

          SECTION 1305.  SECURITIES REPAID IN PART.

          Upon surrender of any Registered Security which is to be repaid in
part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the
expense of the Company, a new Registered Security or Securities of the same
series, of any authorized denomination specified by the Holder, in an aggregate
principal amount equal to and in exchange for the portion of the principal of
such Security so surrendered which is not to be repaid.

                                   ARTICLE FOURTEEN

                          DEFEASANCE AND COVENANT DEFEASANCE

          SECTION 1401.  COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT
DEFEASANCE.

          Except as otherwise specified as contemplated by Section 301 for
Securities of any series, the provisions of this Article Fourteen shall apply to
each series of Securities, and the Company may, at its option, effect defeasance
of the Securities of or within a series under Section 1402, or covenant
defeasance of or within a series under Section 1403 in accordance with the terms
of such Securities and in accordance with this Article.

          SECTION 1402.  DEFEASANCE AND DISCHARGE.

          Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations with respect to such
Outstanding Securities and any related coupons on the date the conditions set
forth in Section 1404 are satisfied (hereinafter, "defeasance").  For this
purpose, such defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Outstanding Securities
and any related coupons, which shall thereafter be deemed to be "Outstanding"
only for the purposes of Section 1405 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Securities and any related coupons and this Indenture
insofar as such Securities and any related coupons are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder:  (A) the rights of Holders of such
Outstanding Securities and any related coupons to receive, solely from the trust
fund described in Section 1404 and as more fully set forth in such Section,
payments in respect of the principal of (and premium, if any) and interest, if
any, on such Securities and any related coupons when such payments are due, (B)
the Company's obligations with respect to such Securities under Sections 304,
305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and (D) this Article Fourteen.  Subject to compliance
with this Article Fourteen, the Company may exercise its option under this
Section 1402 notwithstanding the prior exercise of its option under Section 1403
with respect to such Securities and any related coupons.

<PAGE>
                                         103


          SECTION 1403.  COVENANT DEFEASANCE.

          Upon the Company's exercise under Section 1402 of the option
applicable to this Section 1403 with respect to any Securities of or within a
series, the Company shall be released from its obligations under any covenant
under Article Eight and in Sections 1004 through 1012, and, if specified
pursuant to Section 301, its obligations under any other covenant, with respect
to such Outstanding Securities and any related coupons on and after the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any related coupons shall thereafter be
deemed to be not "Outstanding" for the purposes of any direction, waiver,
consent or declaration or Act of Holders (and the consequences of any thereof)
in connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder (it being understood that such Securities shall
not be deemed Outstanding for financial accounting purposes).  For this purpose,
such covenant defeasance means that, with respect to such Outstanding Securities
and any related coupons, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of reference in any such covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 501(4) or
Section 501(9) or otherwise, as the case may be, but, except as specified above,
the remainder of this Indenture and such Securities and any related coupons
shall be unaffected thereby.  In addition, upon the Company's exercise under
Section 1401 of the option applicable to Section 1403, Sections 501(4) through
(6) shall not constitute Events of Default.

          SECTION 1404.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

          The following shall be the conditions to application of either Section
1402 or Section 1403 to any Outstanding Securities of or within a series and any
related coupons:

          (1)  The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 607 who shall agree to comply with the provisions of this
     Article Fourteen applicable to it) as trust funds in trust for the purpose
     of making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities and any
     related coupons, (A) an amount (in such Currency in which such Securities
     and any related coupons are then specified as payable at Stated Maturity),
     or (B) Government Obligations applicable to such Securities (determined on
     the basis of the Currency in which such Securities are then specified as
     payable at Stated Maturity) which through the scheduled payment of
     principal and interest in respect thereof in accordance with their terms
     will provide, not later than one day before the due date of any payment of
     principal of and 

<PAGE>
                                         104


     premium, if any, and interest, if any, under such Securities and any
     related coupons, money in an amount, or (C) a combination thereof,
     sufficient, in the opinion of a nationally recognized firm of independent
     public accountants expressed in a written certification thereof delivered
     to the Trustee, to pay and discharge, and which shall be applied by the
     Trustee (or other qualifying trustee) to pay and discharge, (i) the
     principal of (and premium, if any) and interest, if any, on such
     Outstanding Securities and any related coupons on the Stated Maturity (or
     Redemption Date, if applicable) of such principal (and premium, if any) or
     installment of interest, if any, and (ii) any mandatory sinking fund
     payments or analogous payments applicable to such Outstanding Securities
     and any related coupons on the day on which such payments are due and
     payable in accordance with the terms of this Indenture and of such
     Securities and any related coupons; PROVIDED that the Trustee shall have
     been irrevocably instructed to apply such money or the proceeds of such
     Government Obligations to said payments with respect to such Securities and
     any related coupons.  Before such a deposit, the Company may give to the
     Trustee, in accordance with Section 1102 hereof, a notice of its election
     to redeem all or any portion of such Outstanding Securities at a future
     date in accordance with the terms of the Securities of such series and
     Article Eleven hereof, which notice shall be irrevocable.  Such irrevocable
     redemption notice, if given, shall be given effect in applying the
     foregoing.

          (2)  No Default or Event of Default with respect to such Securities or
     any related coupons shall have occurred and be continuing on the date of
     such deposit or, insofar as paragraphs (7) and (8) of Section 501 are
     concerned, at any time during the period ending on the 91st day after the
     date of such deposit (it being understood that this condition shall not be
     deemed satisfied until the expiration of such period).

          (3)  No event or condition shall exist that would prevent the Company
     from making payments of the principal of (and premium, if any) or interest
     on the Securities on the date of such deposit or at any time during the
     period ending on the 91st day after the date of such deposit (it being
     understood that this condition shall not be deemed satisfied until the
     expiration of such period).

          (4)  Such defeasance or covenant defeasance shall not result in a
     breach or violation of, or constitute a default under, this Indenture or
     any other material agreement or instrument to which the Company is a party
     or by which it is bound.

          (5)  In the case of an election under Section 1402, the Company shall
     have delivered to the Trustee an Opinion of Counsel stating that (x) the
     Company has received from, or there has been published by, the Internal
     Revenue Service a ruling, or (y) since the date of execution of this
     Indenture, there has been a change in the applicable federal income tax
     law, in either case to the effect that, and based thereon 

<PAGE>
                                         105


     such opinion shall confirm that, the Holders of such Outstanding Securities
     and any related coupons will not recognize income, gain or loss for federal
     income tax purposes as a result of such defeasance and will be subject to
     federal income tax on the same amounts, in the same manner and at the same
     times as would have been the case if such defeasance had not occurred.

          (6)  In the case of an election under Section 1403, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of such Outstanding Securities and any related coupons will not
     recognize income, gain or loss for federal income tax purposes as a result
     of such covenant defeasance and will be subject to federal income tax on
     the same amounts, in the same manner and at the same times as would have
     been the case if such covenant defeasance had not occurred.

          (7)  In the case of an election under either Section 1402 or 1403, the
     Company shall represent to the Trustee that the deposit made by the Company
     pursuant to its election under Section 1402 or 1403 was not made by the
     Company with the intent of preferring the Holders of Securities of any
     series over other creditors of the Company or with the intent of defeating,
     hindering, delaying or defrauding creditors of the Company or others.

          (8)  Notwithstanding any other provisions of this Section, such
     defeasance or covenant defeasance shall be effected in compliance with any
     additional or substitute terms, conditions or limitations in connection
     therewith pursuant to Section 301.

          (9)  The Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for relating to either the defeasance under Section 1402
     or the covenant defeasance under Section 1403 (as the case may be) have
     been complied with.

          SECTION 1405.  DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

          Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1405, the
"Trustee") pursuant to Section 1404 in respect of such Outstanding Securities
and any related coupons shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any related coupons and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to 

<PAGE>
                                         106


the Holders of such Securities and any related coupons of all sums due and to
become due thereon in respect of principal (and premium, if any) and interest,
if any, but such money need not be segregated from other funds except to the
extent required by law.

          Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(1) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 313(b) or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 1404(1) has been made in respect of such Security, or (b) a
Conversion Event occurs as contemplated in Section 313(d) or 313(e) or by the
terms of any Security in respect of which the deposit pursuant to Section
1404(1) has been made, the indebtedness represented by such Security and any
related coupons shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium, if any) and
interest, if any, on such Security as they become due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on the applicable Market Exchange Rate
for such Currency in effect on the third Business Day prior to each payment
date, except, with respect to a Conversion Event, for such Currency in effect
(as nearly as feasible) at the time of the Conversion Event.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any related
coupons.

          Anything in this Article Fourteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in Section 1404 which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

          SECTION 1406.  REINSTATEMENT.

          If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 1405 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and such
Securities and any related coupons shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1402 or 1403, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1405; PROVIDED, HOWEVER, that if the Company makes any
payment of principal of (or premium, if any) or interest, if any, on any such
Security or any related coupon following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
and any related coupons to receive such payment from the money held by the
Trustee or Paying Agent.

                          MEETINGS OF HOLDERS OF SECURITIES

          SECTION 1501.  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

          If Securities of a series are issuable as Bearer Securities, a meeting
of Holders of Securities of such series may be called at any time and from time
to time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such
series.

          SECTION 1502.  CALL, NOTICE AND PLACE OF MEETINGS.

          (a)  The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1501, to be held
at such time and at such place in The City of New York or in London as the
Trustee shall determine.  Notice of every meeting of Holders of Securities of

terms the action proposed to be taken at such meeting, shall be given, in the
manner provided for in Section 106, not less than 21 nor more than 180 days
prior to the date fixed for the meeting.

          (b)  In case at any time the Company, pursuant to a Board Resolution,

of any series shall have requested the Trustee to call a meeting of the Holders
of Securities of such series for any purpose specified in Section 1501, by

                                         108


first publication of the notice of such meeting within 21 days after receipt of
such request or shall not thereafter proceed to cause the meeting to be held as

the amount above specified, as the case may be, may determine the time and the
place in The City of New York or in London for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in paragraph (a)
of this Section.

          SECTION 1503.  PERSONS ENTITLED TO VOTE AT MEETINGS.

          To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders.  The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Person
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

          SECTION 1504.  QUORUM; ACTION.

          The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; PROVIDED, HOWEVER, that, if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of not less than a
specified percentage in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote such specified percentage in principal
amount of the Outstanding Securities of such series shall constitute a quorum. 
In the absence of a quorum within 30 minutes of the time appointed for any such
meeting, the meeting shall, if convened at the request of Holders of Securities
of such series, be dissolved.  In any other case the meeting may be adjourned
for a period of not less than 10 days as determined by the chairman of the
meeting prior to the adjournment of such meeting.  In the absence of a quorum at
any such adjourned meeting, such adjourned meeting may be further adjourned for
a period of not less than 10 days as determined by the chairman of the meeting
prior to the adjournment of such adjourned meeting.  Notice of the reconvening
of any adjourned meeting shall be given as provided in Section 1502(a), except
that such notice need be given only once not less than five days prior to the
date on which the meeting is scheduled to be reconvened.  Notice of the
reconvening of any adjourned meeting shall state expressly the percentage, as
provided above, of the principal amount of the Outstanding Securities of such
series which shall constitute a quorum.

          Subject to the foregoing, at the reconvening of any meeting adjourned
for lack of a quorum the Persons entitled to vote 25% in principal amount of the
Outstanding 

<PAGE>
                                         109


Securities at the time shall constitute a quorum for the taking of any action
set forth in the notice of the original meeting.

          Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of
not less than a majority in principal amount of the Outstanding Securities of
such series; PROVIDED, HOWEVER, that, except as limited by the proviso to
Section 902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which this Indenture
expressly provides may be made, given or taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of not less than such specified percentage in
principal amount of the Outstanding Securities of such series.

          Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

          Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

     (i)  there shall be no minimum quorum requirement for such meeting; and

     (ii) the principal amount of the Outstanding Securities of such series that
vote in favor of such request, demand, authorization, direction, notice,
consent, waiver or other action shall be taken into account in determining
whether such request, demand, authorization, direction, notice, consent, waiver
or other action has been made, given or taken under this Indenture.

          SECTION 1505.  DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT
OF MEETINGS.

          (a)  Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, 

<PAGE>
                                         110


the submission and examination of proxies, certificates and other evidence of
the right to vote, and such other matters concerning the conduct of the meeting
as it shall deem appropriate.  Except as otherwise permitted or required by any
such regulations, the holding of Securities shall be proved in the manner
specified in Section 104 and the appointment of any proxy shall be proved in the
manner specified in Section 104 or by having the signature of the person
executing the proxy witnessed or guaranteed by any trust company, bank or banker
authorized by Section 104 to certify to the holding of Bearer Securities.  Such
regulations may provide that written instruments appointing proxies, regular on
their face, may be presumed valid and genuine without the proof specified in
Section 104 or other proof.

          (b)  The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman.  A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

          (c)  At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of Outstanding
Securities of such series held or represented by him (determined as specified in
the definition of "Outstanding" in Section 101); PROVIDED, HOWEVER, that no vote
shall be cast or counted at any meeting in respect of any Security challenged as
not Outstanding and ruled by the chairman of the meeting to be not Outstanding. 
The chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

          (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

          SECTION 1506.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

          The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of 

<PAGE>
                                         111


all votes cast at the meeting.  A record, at least in duplicate, of the
proceedings of each meeting of Holders of Securities of any series shall be
prepared by the Secretary of the meeting and there shall be attached to said
record the original reports of the inspectors of votes on any vote by ballot
taken thereat and affidavits by one or more persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said
notice was given as provided in Section 1502 and, if applicable, Section 1504. 
Each copy shall be signed and verified by the affidavits of the permanent
chairman and secretary of the meeting and one such copy shall be delivered to
the Company, and another to the Trustee to be preserved by the Trustee, the
latter to have attached thereto the ballots voted at the meeting.  Any record so
signed and verified shall be conclusive evidence of the matters therein stated.

          This Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same Indenture.

          IN WITNESS WHEREOF, the parties hereto have caused this Indenture to
be duly executed all as of the day and year first above written.

                      PERSON ENTITLED TO RECEIVE BEARER SECURITY
                         OR TO OBTAIN INTEREST PAYABLE PRIOR

                            OF SECURITIES TO BE DELIVERED]


          This is to certify that as of the date hereof, and except as set forth
below, the above-captioned Securities held by you for our account (i) are owned
by person(s) that are not citizens or residents of the United States, domestic
partnerships, domestic corporations or any estate or trust the income of which
is subject to United States federal income taxation regardless of its source
("United States person(s)"), (ii) are owned by United States person(s) that are
(a) foreign branches of United States financial institutions (financial
institutions, as defined in United States Treasury Regulations Section
2.165-12(c)(1)(v) are herein referred to as "financial institutions") purchasing
for their own account or for resale, or (b) United States person(s) who acquired
the Securities through foreign branches of United States financial institutions
and who hold the Securities through such United States financial institutions on
the date hereof (and in either case (a) or (b), each such United States
financial institution hereby agrees, on its own behalf or through its agent,
that you may advise Cablevision Systems Corporation or its agent that such
financial institution will comply with the requirements of Section 165(j)(3)(A),
(B) or (C) of the United States Internal Revenue Code of 1986, as amended, and
the regulations thereunder), or (iii) are owned by United States or foreign
financial institution(s) for purposes of resale during the restricted period (as
defined in United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7)),
and, in addition, if the owner is a United States or foreign financial
institution described in clause (iii) above (whether or not also described in
clause (i) or (ii)), this is to further certify that such financial institution
has not acquired the Securities for purposes of resale directly or indirectly to
a United States person or to a person within the United States or its
possessions.

          As used herein, "United States" means the United States of America
(including the states and the District of Columbia); and its "possessions"
include Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, Wake Island
and the Northern Mariana Islands.

          We undertake to advise you promptly by tested telex on or prior to the
date on which you intend to submit your certification relating to the
above-captioned Securities held by you for our account in accordance with your
Operating Procedures if any applicable

<PAGE>

statement herein is not correct on such date, and in the absence of any such
notification it may be assumed that this certification applies as of such date.

          This certificate excepts and does not relate to [U.S.$]__________ of
such interest in the above-captioned Securities in respect of which we are not
able to certify and as to which we understand an exchange for an interest in a
Permanent Global Security or an exchange for and delivery of definitive
Securities (or, if relevant, collection of any interest) cannot be made until we
do so certify.

          We understand that this certificate may be required in connection with
certain tax legislation in the United States.  If administrative or legal
proceedings are commenced or threatened in connection with which this
certificate is or would be relevant, we irrevocably authorize you to produce
this certificate or a copy thereof to any interested party in such proceedings.

    or investigation upon which the statements or opinions contained in such
    certificate or opinion are based;

         In any case where several matters are required to be certified by, or
covered by an opinion of, any specified Person, it is not necessary that all
such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

         Any certificate or opinion of an officer of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 104.  ACTS OF HOLDERS.

         (a)  Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders of the Outstanding Securities of all series or one or more series, as
the case may be, may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders 

<PAGE>

                                22


in person or by agents duly appointed in writing.  If Securities of a series are
issuable as Bearer Securities, any request, demand, authorization, direction,
notice, consent, waiver or other action provided by this Indenture to be given
or taken by Holders of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Sixteen, or a combination of such
instruments and any such record.  Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee and, where it is hereby expressly required,
to the Company.  Such instrument or instruments and any such record (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments or so voting
at any such meeting.  Proof of execution of any such instrument or of a writing
appointing any such agent, or of the holding by any Person of a Security, shall
be sufficient for any purpose of this Indenture and (subject to TIA Section 315)
conclusive in favor of the Trustee and the Company, if made in the manner
provided in this Section.  The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 1606.

         (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient.

         (c)  The ownership of Securities shall be proved by the Security
Register.

         (d)  The principal amount and serial numbers of Bearer Securities held
by any Person, and the date of holding the same, may be proved by the production
of such Bearer Securities or by a certificate executed, as depositary, by any
trust company, bank, banker or other depositary, wherever situated, if such
certificate shall be deemed by the Trustee to be satisfactory, showing that at
the date therein mentioned such Person had on deposit with such depositary, or
exhibited to it, the Bearer Securities therein described; or such facts may be
proved by the certificate or affidavit of the Person holding such Bearer
Securities, if such certificate or affidavit is deemed by the Trustee to be
satisfactory.  The Trustee and the Company may assume that such ownership of any
Bearer Security continues until (1) another certificate or affidavit bearing a
later date issued in respect of the same Bearer Security is produced, or
(2) such Bearer Security is produced to the Trustee by some other Person, or
(3) such Bearer Security is surrendered in exchange for a Registered Security,
or (4) such Bearer Security is no longer Outstanding.  The principal amount and
serial numbers of Bearer Securities held by any Person, and the date of holding
the same, may also be proved in any other manner that the Trustee deems
sufficient.

         (e)  If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the 

<PAGE>

                                23


Company may, at its option, by or pursuant to a Board Resolution, fix in advance
a record date for the determination of such Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act,
but the Company shall have no obligation to do so.  Notwithstanding TIA
Section 316(c), any such record date shall be the record date specified in or
pursuant to such Board Resolution, which shall be a date not more than 30 days
prior to the first solicitation of Holders generally in connection therewith and
no later than the date such solicitation is completed.  If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Securities then Outstanding have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other Act, and for that purpose the Securities then Outstanding shall be
computed as of such record date; PROVIDED that no such request, demand,
authorization, direction, notice, consent, waiver or other Act by the Holders on
such record date shall be deemed effective unless it shall become effective
pursuant to the provisions of this Indenture not later than six months after the
record date.

         (f)  Any request, demand, authorization, direction, notice, consent,
waiver or other Act by the Holder of any Security shall bind every future Holder
of the same Security or the Holder of every Security issued upon the
registration of transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done, suffered or omitted to be done by the Trustee, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
action is made upon such Security.

         SECTION 105.  NOTICES, ETC. TO TRUSTEE AND COMPANY.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1)  the Trustee by any Holder, the Agents of the Banks or the Company
    shall be sufficient for every purpose hereunder if made, given, furnished
    or delivered, in writing, to or with the Trustee at its Corporate Trust
    Office, Attention:  Corporate Trust Trustee Administration; or

         (2)  the Company by the Trustee or by any Holder shall be sufficient
    for every purpose hereunder (unless otherwise herein expressly provided) if
    made, given, furnished or delivered, in writing, to the Company addressed
    to it c/o Cablevision Systems Corporation, One Media Crossways, Woodbury,
    New York 11797, Attention:  Secretary, or at any other address previously
    furnished in writing to the Trustee by the Company.

                                24


         SECTION 106.  NOTICE TO HOLDERS; WAIVER.

         Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder affected by such event,
at his address as it appears in the Security Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice.  In any case where notice to Holders of Registered Securities is given
by mail, neither the failure to mail such notice, nor any defect in any notice
so mailed, to any particular Holder shall affect the sufficiency of such notice
with respect to other Holders of Registered Securities or the sufficiency of any
notice to Holders of Bearer Securities given as provided.  Any notice mailed to
a Holder in the aforesaid manner shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

         In case, by reason of the suspension of or irregularities in regular
mail service or by reason of any other cause, it shall be impractical to mail
notice of any event to Holders of Registered Securities when such notice is
required to be given pursuant to any provision of this Indenture, then any
manner of giving such notice as shall be satisfactory to the Trustee shall be
deemed to be sufficient giving of such notice for every purpose hereunder.

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given to Holders of Bearer Securities if published in an
Authorized Newspaper in The City of New York and in such other city or cities as
may be specified in such Securities on a Business Day at least twice, the first
such publication to be not earlier than the earliest date, and not later than
the latest date, prescribed for the giving of such notice.  Any such notice
shall be deemed to have been given on the date of the first such publication.

         In case, by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause, it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither the failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of such notice with
respect to other Holders of Bearer Securities or the sufficiency of any notice
to Holders of Registered Securities given as provided herein.

<PAGE>

                                25


         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

         Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

         SECTION 107.  CONFLICT OF ANY PROVISION OF INDENTURE WITH TRUST
INDENTURE ACT.

         If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by TIA Sections 310 to 318,
inclusive, or conflicts with any provision (an "incorporated provision")
required by or deemed to be included in this Indenture by operation of such TIA
Sections, such imposed duties or incorporated provision shall control.  If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or excluded, as the case may
be.

         SECTION 108.  EFFECT OF HEADINGS AND TABLE OF CONTENTS.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         SECTION 109.  SUCCESSORS AND ASSIGNS.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         SECTION 110.  SEPARABILITY CLAUSE.

         In case any provision in this Indenture or in any Security or coupon
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

         SECTION 111.  BENEFITS OF INDENTURE.

         Nothing in this Indenture or in the Securities or coupons, express or
implied, shall give to any Person, other than the parties hereto, any
Authenticating Agent, any Paying Agent, any Securities Registrar, any holders of
Senior Indebtedness and their successors 

<PAGE>

                                26

equitable right, remedy or claim under this Indenture.

         SECTION 112.  GOVERNING LAW.

         This Indenture and the Securities and coupons shall be governed by 
and construed in accordance with the laws of the State of New York without 
regard to conflicts of laws principles.  This Indenture is subject to the 
provisions of the Trust Indenture Act that are required to be part of this 
Indenture and shall, to the extent applicable, be governed by such provisions.

         SECTION 113.  LEGAL HOLIDAYS.

         In any case where any Interest Payment Date, Redemption Date, sinking
fund payment date or Stated Maturity or Maturity of any Security shall not be a
Business Day at any Place of Payment, then (notwithstanding any other provision
of this Indenture or of any Security or coupon other than a provision in the
Securities of any series which specifically states that such provision shall
apply in lieu of this Section), payment of principal (or premium, if any) or
interest, if any, need not be made at such Place of Payment on such date, but
may be made on the next succeeding Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or Redemption
Date or sinking fund payment date, or at the Stated Maturity or Maturity;
PROVIDED that no interest shall accrue for the period from and after such
Interest Payment Date, Redemption Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

         SECTION 114.  NO RECOURSE AGAINST OTHERS.

         A director, officer, employee or stockholder, as such, of the Company
shall not have any liability for any obligations of the Company under the
Securities or this Indenture or for any claim based on, in respect of or by
reason of such obligations or their creation.  Each Holder by accepting any of
the Securities waives and releases all such liability.

in bearer form shall have interest coupons attached.

             TRUSTEE'S CERTIFICATE OF AUTHENTICATION

         Dated:  ____________________

         This is one of the Securities of the series designated therein
    referred to in the within-mentioned Indenture.

                                  THE BANK OF NEW YORK,
                                                 as Trustee


                                  By _____________________________
                                       Authorized Signatory

         SECTION 203.  SECURITIES ISSUABLE IN GLOBAL FORM.

 
         If Securities of or within a series are issuable in global form, as 
specified as contemplated by Section 301, then any such Security shall 
represent such of the Outstanding Securities of such series as shall be 
specified therein and may provide that it shall represent the aggregate 
amount of Outstanding Securities of such series from time to time endorsed 
thereon and that the aggregate amount of Outstanding Securities of such 
series represented thereby may from time to time be increased or decreased to 
reflect exchanges.  Any endorsement of a Security in global form to reflect 
the amount, or any increase or decrease in the amount, of Outstanding 
Securities represented thereby shall be made by the Trustee in such manner 
and upon instructions given by such Person or Persons as shall be specified 
therein or in the Company Order to be delivered to the Trustee pursuant to 
Section 303 or Section 305.  Subject to the provisions of Section 303 and, if 
applicable, Section 305, the Trustee shall deliver and redeliver any Security 
in permanent global form in the manner and upon instructions given by the 
Person or Persons specified therein or in the applicable Company Order.  If a 
Company Order pursuant to Section 303 or Section 305 has been, or 
simultaneously is, delivered, any instructions by the Company with respect to 
endorsement or delivery or redelivery of a Security in global form shall be 
in writing but need not comply with Section 102 and need not be accompanied 
by an Opinion of Counsel.
 

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

                                29


         Notwithstanding the provisions of Section 308, unless otherwise
specified as contemplated by Section 301, payment of principal of (and premium,
if any) and interest, if any, on any Security in permanent global form shall be
made to the Person or Persons specified therein.

         Notwithstanding the provisions of Section 310 and except as provided
in the preceding paragraph, the Company, the Trustee and any agent of the
Company and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent Global Security (i) in the
case of a permanent Global Security in registered form, the Holder of such
permanent Global Security in registered form, or (ii) in the case of a permanent
Global Security in bearer form, Euroclear or Cedel.

         SECTION 204.  FORM OF LEGEND FOR BOOK-ENTRY SECURITIES.

         Any Global Security authenticated and delivered hereunder shall bear a
legend (which would be in addition to any other legends required in the case of
a Restricted Security) in substantially the following form:

         THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE
    HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITORY OR A
    NOMINEE THEREOF.  THIS SECURITY MAY NOT BE EXCHANGED IN WHOLE OR IN PART
    FOR A SECURITY REGISTERED, AND NO TRANSFER OF THIS SECURITY IN WHOLE OR IN
    PART MAY BE REGISTERED, IN THE NAME OF ANY PERSON OTHER THAN SUCH
    DEPOSITORY OR ITS NOMINEE EXCEPT IN THE LIMITED CIRCUMSTANCES DESCRIBED IN
    THE INDENTURE.


         UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
    OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK 10041)
    TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
    PAYMENT AND SUCH CERTIFICATE ISSUED IN EXCHANGE FOR THIS CERTIFICATE IS
    REGISTERED IN THE NAME OF CEDE & CO., OR SUCH OTHER NAME AS REQUESTED BY AN
    AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, ANY TRANSFER,
    PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
    WRONGFUL, SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
    HEREIN.

    of Default of the Company with respect to Securities of the series, whether

         (21) the specific terms of the depository arrangement with respect to
    any portion of a series of Securities to be represented by a Global
    Security pursuant to Section 304; and

         (22) any other terms, conditions, rights and preferences (or
    limitations on such rights and preferences) relating to the series (which
    terms shall not be inconsistent with the requirements of the Trust
    Indenture Act or the provisions of this Indenture).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto.  Not all Securities of any one series need be issued at the same time,
and, unless otherwise provided, a series may be reopened for issuances of
additional Securities of such series.

         If any of the terms of the series are established by action taken
pursuant to one or more Board Resolutions, such Board Resolutions shall be
delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms of the series.

         SECTION 302.  DENOMINATIONS.

         The Securities of each series shall be issuable in such denominations

<PAGE>

                                34


other than Securities issued in global form (which may be of any denomination),
shall be issuable in denominations of $1,000 and any integral multiple thereof.

         SECTION 303.  EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by any one of the following:  its Chairman, Chief
Executive Officer, its President or one of its Vice Presidents, and attested by
one of its Vice Presidents or its Secretary or one of its Assistant Secretaries.
The signature of any of these officers on the Securities or coupons may be
manual or facsimile.

         Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

         At any time and from time to time after the execution and delivery 
of this Indenture, the Company may deliver Securities of any series together 
with any coupon appertaining thereto, executed by the Company to the Trustee 
for authentication, together with a Company Order for the authentication and 
delivery of such Securities, and the Trustee in accordance with such Company 
Order shall authenticate and make available for delivery such Securities; 
PROVIDED, HOWEVER, that, in connection with its original issuance, no Bearer 
Security shall be mailed or otherwise delivered to any location in the United 
States; and PROVIDED FURTHER that, unless otherwise specified with respect to 
any series of Securities pursuant to Section 301, a Bearer Security may be 
delivered in connection with its original issuance only if the Person 
entitled to receive such Bearer Security shall have furnished a certificate 
in the form set forth in Exhibit B-1 to this Indenture, dated no earlier than 
15 days prior to the earlier of the date on which such Bearer Security is 
delivered and the date on which any temporary Security first becomes 
exchangeable for such Bearer Security in accordance with the terms of such 
temporary Security and this Indenture.  If any Security shall be represented 
by a permanent global Bearer Security, then, for purposes of this Section and 
Section 305, the notation of a beneficial owner's interest therein upon 
original issuance of such Security or upon exchange of a portion of a 
temporary Global Security shall be deemed to be delivery in connection with 
its original issuance of such beneficial owner's interest in such permanent 
Global Security.  Except as permitted by Section 307, the Trustee shall not 
authenticate and make available for delivery any Bearer Security unless all 
appurtenant coupons for interest then matured have been detached and 
cancelled.  If not all the Securities of any series are to be issued at one 
time and if the Board Resolution or supplemental indenture establishing such 
series shall so permit, such Company Order may set forth procedures 
acceptable to the Trustee for the issuance of such Securities and determining 
terms of particular Securities of such series such as interest rate, stated 
maturity, date of issuance and date from which interest shall accrue.

                                35


         In authenticating such Securities, and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to TIA Sections 315(a)
through 315(d)) shall be fully protected in relying upon, an Opinion of Counsel
stating:

         (a)  that the form or forms of such Securities and any coupons have
    been established in conformity with the provisions of this Indenture;

         (b)  that the terms of such Securities and any coupons have been
    established in conformity with the provisions of this Indenture;

 
         (c)  that such Securities, together with any coupons appertaining
    thereto, when completed by appropriate insertions and executed and
    delivered by the Company to the Trustee for authentication in accordance
    with this Indenture, authenticated and made available for delivery by the 
    Trustee in accordance with this Indenture and issued by the Company in the
    manner and subject to any conditions specified in such Opinion of Counsel, 
    will constitute the legal, valid and binding obligations of the Company,
    enforceable in accordance with their terms, subject to applicable
    bankruptcy, insolvency, reorganization and other similar laws of general
    applicability relating to or affecting the enforcement of creditors'
    rights, to general equitable principles and to such other qualifications as
    such counsel shall conclude do not materially affect the rights of Holders
    of such Securities and any coupons;
 

         (d)  that all laws and requirements in respect of the execution and
    delivery by the Company of such Securities, any coupons and of the
    supplemental indentures, if any, have been complied with and that
    authentication and delivery of such Securities and any coupons and the
    execution and delivery of the supplemental indenture, if any, by the
    Trustee will not violate the terms of the Indenture;

         (e)  that the Company has the corporate power to issue such Securities
    and any coupons, and has duly taken all necessary corporate action with
    respect to such issuance; and

         (f)  that the issuance of such Securities and any coupons will not
    contravene the articles of incorporation or by-laws of the Company or
    result in any violation of any of the terms or provisions of any law or
    regulation or of any indenture, mortgage or other agreement known to such
    Counsel by which the Company is bound.

         Notwithstanding the provisions of Section 301 and of the preceding two
paragraphs, if not all the Securities of any series are to be issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to the preceding 

<PAGE>

                                36


two paragraphs prior to or at the time of issuance of each Security, but such
documents shall be delivered prior to or at the time of issuance of the first
Security of such series.

         The Trustee shall not be required to authenticate and make available 
for delivery any such Securities if the issue of such Securities pursuant to 
this Indenture will affect the Trustee's own rights, duties or immunities 
under the Securities and this Indenture or otherwise in a manner which is not 
reasonably acceptable to the Trustee.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture. 
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 311 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of
this Indenture such Security shall be deemed never to have been authenticated
and delivered hereunder and shall never be entitled to the benefits of this
Indenture.

         SECTION 304.   BOOK-ENTRY SECURITIES.

         (a)  The Securities of a series may be issuable in whole or in part in
the form of one or more Global Securities ("Book-Entry Securities") deposited
with, or on behalf of, a Depository (the "Depository").  In the case of
Book-Entry Securities, one or more Global Securities will be issued in a
denomination or aggregate denomination equal to the portion of the aggregate
principal amount of Outstanding Securities of the series to be represented by
such Global Security or Global Securities.  Unless otherwise provided as
contemplated by Section 301, the additional provisions set forth in this Section
304 shall apply to Book-Entry Securities.

         (b)  Book-Entry Securities will be deposited with, or on behalf of,
the Depository, and registered in the name of the Depository's nominee, for
credit to the respective accounts of institutions that have accounts with the
Depository or its nominee ("Participants"); PROVIDED that Book-Entry Securities
purchased by persons outside the United States may be credited to or through
accounts maintained at the Depository by or on behalf of Euroclear or Cedel. 
The accounts to be credited will be designated by the underwriters or 

<PAGE>

                                37


agents of such Securities or, if such Securities are offered and sold directly
by the Company, by the Company.  Ownership of beneficial interests in Book-Entry
Securities will be limited to Persons that may hold interests through
Participants and will be shown on records maintained by the Depository or its
nominee for such Book-Entry Security.

         Participants shall have no rights under any indenture supplemental
hereto with respect to any Book-Entry Security held on their behalf by the
Depository, or the Trustee as its custodian, or under the Book-Entry Security,
and the Depository may be treated by the Company, the Trustee and any agent of
the Company or the Trustee as the absolute owner of the Book-Entry Security for
all purposes whatsoever.  Notwithstanding the foregoing, nothing in any such
indenture shall prevent the Company, the Trustee or any agent of the Company or
the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between the Depository
and its Participants, the operation of customary practices governing the
exercise of the rights of a Holder of any Security.

         (c)  Transfers of Book-Entry Securities shall be limited to transfers
in whole, but not in part, to the Depository, its successors or their respective
nominees.  Interests of beneficial owners in the Global Securities may be
transferred or exchanged for Bearer Securities in exchange for their beneficial
interests in a Book-Entry Security only if (i) the Depository advises the
applicable Trustee in writing that it is no longer willing or able to discharge
properly its responsibilities with respect to such Book-Entry Security and it is
unable to locate a qualified successor, (ii) the Company, at its option, elects
to terminate the book-entry system by executing and delivering to the Trustee
and the Depository a notice to such effect, or (iii) there shall have occurred
and be continuing a Default or Event of Default with respect to the Securities
represented by such Book-Entry Security.

         (d)  In connection with any transfer or exchange of a portion of the
beneficial interest in any Book-Entry Security to beneficial owners pursuant to
paragraph (c) above, the Security Registrar shall (if one or more Bearer
Securities are to be issued) reflect on its books and records the date and a
decrease in the principal amount of the Book-Entry Security in an amount equal
to the principal amount of the beneficial interest in the Book-Entry Security to
be transferred, and the Company shall execute, and the Trustee shall
authenticate and deliver, one or more Bearer Securities of like tenor and
principal amount of authorized denominations.

         (e)  In connection with the transfer of Book-Entry Securities as an
entirety to beneficial owners pursuant to paragraph (c) above, the Book-Entry
Securities shall be deemed to be surrendered to the Trustee for cancellation and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depository in exchange for its
beneficial interest in the Book-Entry Securities, an equal aggregate principal
amount of Bearer Securities of like tenor of authorized denominations.

         (f)  The Holder of any Book-Entry Security may grant proxies and
otherwise authorize any person, including Participants and Persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under the applicable Indenture or the Securities.


         SECTION 305.  TEMPORARY SECURITIES.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are typewritten, printed, lithographed,
engraved or otherwise produced by any combination of these methods, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as evidenced by their
execution of such Securities.  Such temporary Securities may be in global form.

         Except in the case of temporary Securities in global form that are not
issued as Book-Entry Securities as provided in Section 304 (which shall be
exchanged in accordance with the provisions of the following paragraphs), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay.  After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (accompanied by any unmatured coupons appertaining thereto), the Company
shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations; PROVIDED, HOWEVER, that no Bearer Security shall be
delivered in exchange for a temporary Registered Security; and PROVIDED FURTHER
that a Bearer Security shall be delivered in exchange for a temporary Bearer
Security only in compliance with the conditions set forth in Section 303.  Until
so exchanged the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

         If temporary Securities of any series are issued in global form (other
than Securities issued as Book-Entry Securities as provided in Section 304), any
such temporary Global Security shall, unless otherwise provided therein, be
delivered to the London office of a depositary or common depositary (the "Common
Depositary"), for the benefit of Euroclear and Cedel, for credit to the
respective accounts of the beneficial owners of such Securities (or to such
other accounts as they may direct).

<PAGE>

                                39


         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security that is not issued as a Book-Entry Security as provided in Section 304
(the "Exchange Date"), the Company shall deliver to the Trustee definitive
Securities, in aggregate principal amount equal to the principal amount of such
temporary Global Security, executed by the Company.  On or after the Exchange
Date such temporary Global Security shall be surrendered by the Common
Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged.  The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof; PROVIDED,
HOWEVER, that, unless otherwise specified in such temporary Global Security,
upon such presentation by the Common Depositary, such temporary Global Security
is accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary Global Security held for
its account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by Cedel as to the portion of such temporary Global
Security held for its account then to be exchanged, each in the form set forth
in Exhibit B-2 to this Indenture (or in such other form as may be established
pursuant to Section 301); and PROVIDED FURTHER that Bearer Securities shall be
delivered in exchange for a portion of a temporary Global Security only in
compliance with the requirements of Section 303.

         Unless otherwise specified in such temporary Global Security that is
not issued as a Book-Entry Security as provided in Section 304, the interest of
a beneficial owner of Securities of a series in a temporary Global Security
shall be exchanged for definitive Securities of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
Cedel, as the case may be, to request such exchange on his behalf and delivers
to Euroclear or Cedel, as the case may be, a certificate in the form set forth
in Exhibit B-1 to this Indenture (or in such other form as may be established
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange
Date, copies of which certificate shall be available from the offices of
Euroclear and Cedel, the Trustee, any Authenticating Agent appointed for such
series of Securities and each Paying Agent.  Unless otherwise specified in such
temporary Global Security, any such exchange shall be made free of charge to the
beneficial owners of such temporary Global Security, except that a Person
receiving definitive Securities must bear the cost of insurance, postage,
transportation and the like in the event that such Person does not take delivery
of such definitive Securities in person at the offices of Euroclear or Cedel. 
Bearer Securities in bearer form to be delivered 

<PAGE>

                                40


in exchange for any portion of a temporary Global Security shall be delivered
only outside the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series, including temporary Global Securities (whether or not
issued as Book-Entry Securities as provided in Section 304), shall in all
respects be entitled to the same benefits under this Indenture as definitive
Securities of the same series and of like tenor authenticated and delivered
hereunder, except that, unless otherwise specified as contemplated by
Section 301, interest payable on a temporary Global Security (other than
Securities issued as Book-Entry Securities as provided in Section 304) on an
Interest Payment Date for Securities of such series occurring prior to the
applicable Exchange Date shall be payable to Euroclear and Cedel on such
Interest Payment Date upon delivery by Euroclear and Cedel to the Trustee of a
certificate or certificates in the form set forth in Exhibit B-2 to this
Indenture (or in such other form as may be established pursuant to Section 301),
for credit without further interest thereon on or after such Interest Payment
Date to the respective accounts of the Persons who are the beneficial owners of
such temporary Global Security on such Interest Payment Date and who have each
delivered to Euroclear or Cedel, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth in Exhibit B-1 to this Indenture (or in such
other form as may be established pursuant to Section 301).  Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section and of the third paragraph of Section 303 of this
Indenture and the interests of the Persons who are the beneficial owners of the
temporary Global Security with respect to which such certification was made will
be exchanged for definitive Securities of the same series and of like tenor on
the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal (or premium, if
any) or interest, if any, owing with respect to a beneficial interest in a
temporary Global Security will be made unless and until such interest in such
temporary Global Security shall have been exchanged for an interest in a
definitive Security.  Any interest so received by Euroclear and Cedel and not
paid as herein provided shall be returned to the Trustee immediately prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Company in accordance with Section 1003.

         SECTION 306.  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

         The Company shall cause to be kept at the Corporate Trust Office of
the Trustee a register for each series of Securities (the registers maintained
in such office of the Trustee and in any other office or agency designated
pursuant to Section 1002 being herein sometimes referred to as the "Security
Register") in which, subject to such reasonable regulations as it may prescribe,
the Company shall provide for the registration of Registered 

<PAGE>

                                41


Securities and of transfers of Registered Securities.  The Trustee is hereby
initially appointed "Security Registrar" for the purpose of registering
Registered Securities and transfers of Registered Securities as herein provided.

         Except as otherwise described in this Article Three, upon surrender
for registration of transfer of any Registered Security of any series at the
office or agency in a Place of Payment for that series, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount.

         At the option of the Holder, Registered Securities of any series may 
be exchanged for other Registered Securities of the same series, of any 
authorized denominations and of a like aggregate principal amount, upon 
surrender of the Registered Securities to be exchanged at such office or 
agency. Whenever any Registered Securities are so surrendered for exchange, 
the Company shall execute, and the Trustee shall authenticate and make 
available for delivery, the Registered Securities which the Holder making the 
exchange is entitled to receive.  Unless otherwise specified with respect to 
any series of Securities as contemplated by Section 301 or Section 304, 
Bearer Securities may not be issued in exchange for Registered Securities.

         If (but only if) expressly permitted in or pursuant to the applicable
Board Resolution and (subject to Section 303) set forth in the applicable
Officers' Certificate, or in any indenture supplemental hereto, delivered as
contemplated by Section 301, at the option of the Holder, Bearer Securities of
any series may be exchanged for Registered Securities of the same series of any
authorized denomination and of a like aggregate principal amount and tenor, upon
surrender of the Bearer Securities to be exchanged at any such office or agency,
with all unmatured coupons and all matured coupons in default thereto
appertaining.  If the Holder of a Bearer Security is unable to produce any such
unmatured coupon or coupons or matured coupon or coupons in default, any such
permitted exchange may be effected if the Bearer Securities are accompanied by
payment in funds acceptable to the Company in an amount equal to the face amount
of such missing coupon or coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there is furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless.  If thereafter the Holder of such Security shall
surrender to any Paying Agent any such missing coupon in respect of which such a
payment shall have been made, such Holder shall be entitled to receive the
amount of such payment; PROVIDED, HOWEVER, that, except as otherwise provided in
Section 1002, interest represented by coupons shall be payable only upon
presentation and surrender of those coupons at an office or agency located
outside the United States.  Notwithstanding the foregoing, in case a Bearer
Security of any series is surrendered at any such office or agency in a
permitted exchange for a Registered Security of the same series and like tenor
after the close of business at such 

<PAGE>

                                42


office or agency on (i)  any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or
(ii) any Special Record Date and before the opening of business at such office
or agency on the related proposed date for payment of Defaulted Interest, such
Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture.

         Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive, and the Trustee
shall cancel the Bearer Securities so transferred.  In the case of an exchange
of Bearer Securities for an interest in a Book-Entry Security, the Security
Registrar shall reflect on the Register the date and an increase in the
principal amount of the Bearer Securities to be transferred, and the Trustee
shall cancel the Bearer Securities so transferred.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security (other than
Securities issued as Book-Entry Securities as provided in Section 304) shall be
exchangeable only as provided in this paragraph.  If any beneficial owner of an
interest in a permanent Global Security is entitled to exchange such interest
for Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent Global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall deliver to the Trustee definitive Securities in aggregate
principal amount equal to the principal amount of such beneficial owner's
interest in such permanent Global Security, executed by the Company.  On or
after the earliest date on which such interests may be so exchanged, such
permanent Global Security shall be surrendered by the Common Depositary or such
other depositary as shall be specified in the Company Order with respect thereto
to the Trustee, as the Company's agent for such purpose, to be exchanged, in
whole or from time to time in part, for definitive Securities without charge,
and the Trustee shall authenticate and deliver, in exchange for each portion of
such permanent Global Security, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such permanent Global Security to be exchanged which,
unless the Securities of the series are not issuable both as Bearer Securities
and as Registered Securities, as specified as contemplated by Section 301, shall
be in the form of Bearer Securities or Registered Securities, or any combination
thereof, as shall be specified by the beneficial owner thereof; PROVIDED,
HOWEVER, that no such exchanges may occur during a period beginning at the
opening of business 15 days before any selection of Securities to be 


<PAGE>

                                43


redeemed and ending on the relevant Redemption Date if the Security for which
exchange is requested may be among those selected for redemption; and PROVIDED
FURTHER that no Bearer Security delivered in exchange for a portion of a
permanent Global Security shall be mailed or otherwise delivered to any location
in the United States.  If a Registered Security is issued in exchange for any
portion of a permanent Global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and before the opening of business
at such office or agency on the related proposed date for payment of Defaulted
Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent Global
Security is payable in accordance with the provisions of this Indenture.

         All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Securities
surrendered upon such registration of transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Security
Registrar) be duly endorsed, or be accompanied by a written instrument of
transfer, in form satisfactory to the Company and the Security Registrar, duly
executed by the Holder thereof or his attorney duly authorized in writing.

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to pay all documentary, stamp, similar issue or transfer taxes or other
governmental charges that may be imposed in connection with any registration of
transfer or exchange of Securities, other than exchanges pursuant to
Section 305, 906, 1107 or 1405 not involving any transfer.

         The Company shall not be required (i) to issue, register the transfer
of or exchange Securities of any series during a period beginning at the opening
of business 15 days before the day of the selection for redemption of Securities
of that series under Section 1103 or 1303 and ending at the close of business on
(A) if Securities of the series are issuable only as Registered Securities, the
day of the mailing of the relevant notice of redemption and (B) if Securities of
the series are issuable as Bearer Securities, the day of the first publication
of the relevant notice of redemption or, if Securities of the series are also
issuable as Registered Securities and there is no publication, the mailing of
the relevant notice of redemption, or (ii) to register the transfer of or
exchange any Registered Security so selected for redemption in whole or in part,
except the unredeemed portion of any 

<PAGE>

                                44


Security being redeemed in part, or (iii) to exchange any Bearer Security so
selected for redemption except that such a Bearer Security may be exchanged for
a Registered Security of that series and like tenor; PROVIDED that such
Registered Security shall be simultaneously surrendered for redemption, or
(iv) to issue, register the transfer of or exchange any Security which has been
surrendered for repayment at the option of the Holder, except the portion, if
any, of such Security not to be so repaid.

         SECTION 307.  MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

         If any mutilated Security or a Security with a mutilated coupon
appertaining to it is surrendered to the Trustee together with, in proper cases,
such security or indemnity as may be required by the Company or the Trustee to
save each of them and any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding, with coupons corresponding
to the coupons, if any, appertaining to the surrendered Security, or, in case
any such mutilated Security or coupon has become or is about to become due and
payable, the Company in its discretion may, instead of issuing a new Security,
with coupons corresponding to the coupons, if any, appertaining to the
surrendered Security, pay such Security or coupon.

         If there shall be delivered to the Company and to the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any
Security or coupon and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company or the Trustee that such Security or coupon has
been acquired by a bona fide purchaser, the Company shall execute and upon
Company Order the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security for which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not
destroyed, lost or stolen), a new Security of the same series and of like tenor
and principal amount and bearing a number not contemporaneously outstanding,
with coupons corresponding to the coupons, if any, appertaining to such
destroyed, lost or stolen Security or to the Security to which such destroyed,
lost or stolen coupon appertains.

         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such mutilated, destroyed, lost or stolen Security or to the
Security to which such mutilated, destroyed, lost or stolen coupon appertains,
pay such Security or coupon; PROVIDED, HOWEVER, that payment of principal of
(and premium, if any) and interest, if any, on Bearer Securities shall, except
as otherwise provided in Section 1002, be payable only at an office or agency
located outside the United States and, unless otherwise specified as
contemplated by Section 301, any 

<PAGE>

                                45


interest on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to pay all documentary, stamp or
similar issue or transfer taxes or other governmental charges that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee) connected therewith.

         Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen
Security or in exchange for a Security to which a mutilated, destroyed, lost or
stolen coupon appertains, shall constitute an original additional contractual
obligation of the Company, whether or not the mutilated, destroyed, lost or
stolen Security and its coupons, if any, or the mutilated, destroyed, lost or
stolen coupon shall be at any time enforceable by anyone, and shall be entitled
to all the benefits of this Indenture equally and proportionately with any and
all other Securities of that series and their coupons, if any, duly issued
hereunder.

         The provisions of this Section 307 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities or
coupons.

         SECTION 308.  PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED; OPTIONAL
INTEREST RESET.

         (a)  Unless otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest, if any, on any Registered
Security which is payable, and is punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 1002; PROVIDED, HOWEVER,
that each installment of interest, if any, on any Registered Security may at the
Company's option be paid by (i) mailing a check for such interest, payable to or
upon the written order of the Person entitled thereto pursuant to Section 310,
to the address of such Person as it appears on the Security Register or
(ii) transfer to an account located in the United States maintained by the
payee.

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest, if any, may be made, in
the case of a Bearer Security, by transfer to an account located outside the
United States maintained by the payee.

         Unless otherwise provided as contemplated by Section 301, every
permanent Global Security (other than Book-Entry Securities issued as provided
in Section 304) will 

<PAGE>

                                46


provide that interest, if any, payable on any Interest Payment Date will be paid
to each of Euroclear and Cedel with respect to that portion of such permanent
Global Security held for its account by the Common Depositary, for the purpose
of permitting each of Euroclear and Cedel to credit the interest, if any,
received by it in respect of such permanent Global Security to the accounts of
the beneficial owners thereof.

         Any interest on any Registered Security of any series which is
payable, but is not punctually paid or duly provided for, on any Interest
Payment Date shall forthwith cease to be payable to the Holder on the relevant
Regular Record Date by virtue of having been such Holder, and such defaulted
interest and, if applicable, interest on such defaulted interest (to the extent
lawful) at the rate specified in the Securities of such series (such defaulted
interest and, if applicable, interest thereon herein collectively called
"Defaulted Interest") may be paid by the Company, at its election in each case,
as provided in Subsection (1) or (2) below:

         (1)  The Company may elect to make payment of any Defaulted Interest
    to the Persons in whose names the Registered Securities of such series (or
    their respective Predecessor Securities) are registered at the close of
    business on a Special Record Date for the payment of such Defaulted
    Interest, which shall be fixed in the following manner.  The Company shall
    notify the Trustee in writing of the amount of Defaulted Interest proposed
    to be paid on each Registered Security of such series and the date of the
    proposed payment, and at the same time the Company shall deposit with the
    Trustee an amount of money in the Currency in which the Securities of such
    series are payable (except as otherwise specified pursuant to Section 301
    for the Securities of such series and except, if applicable, as provided in
    Sections 313(b), 313(d) and 313(e)) equal to the aggregate amount proposed
    to be paid in respect of such Defaulted Interest or shall make arrangements
    satisfactory to the Trustee for such deposit on or prior to the date of the
    proposed payment, such money when deposited to be held in trust for the
    benefit of the Persons entitled to such Defaulted Interest as in this
    Subsection provided.  Thereupon the Trustee shall fix a Special Record Date
    for the payment of such Defaulted Interest which shall be not more than 15
    days and not less than 10 days prior to the date of the proposed payment
    and not less than 10 days after the receipt by the Trustee of the notice of
    the proposed payment.  The Trustee shall promptly notify the Company of
    such Special Record Date and, in the name and at the expense of the
    Company, shall cause notice of the proposed payment of such Defaulted
    Interest and the Special Record Date therefor to be given in the manner
    provided in Section 106, not less than 10 days prior to such Special Record
    Date.  Notice of the proposed payment of such Defaulted Interest and the
    Special Record Date therefor having been so given, such Defaulted Interest
    shall be paid to the Persons in whose name the Registered Securities of
    such series (or their respective Predecessor Securities) are registered at
    the close of business on such 

<PAGE>

                                47


    Special Record Date and shall no longer be payable pursuant to the
    following Subsection (2).

         (2)  The Company may make payment of any Defaulted Interest on the
    Registered Securities of any series in any other lawful manner not
    inconsistent with the requirements of any securities exchange on which such
    Securities may be listed, and upon such notice as may be required by such
    exchange, if, after notice given by the Company to the Trustee of the
    proposed payment pursuant to this clause, such manner of payment shall be
    deemed practicable by the Trustee.

         (b)  The provisions of this Section 308(b) may be made applicable to
any series of Securities pursuant to Section 301 (with such modifications,
additions or substitutions as may be specified pursuant to such Section 301). 
The interest rate (or the spread or spread multiplier used to calculate such
interest rate, if applicable) on any Security of such series may be reset by the
Company on the date or dates specified on the face of such Security (each an
"Optional Reset Date").  The Company may exercise such option with respect to
such Security by notifying the Trustee of such exercise at least 50 but not more
than 60 days prior to an Optional Reset Date for such Note, which such notice
shall contain such information as may be required by the Trustee to transmit the
Reset Notice as hereinafter defined).  Not later than 40 days prior to each
Optional Reset Date, the Trustee shall transmit, in the manner provided for in
Section 106, to the Holder of any such Security a notice (the "Reset Notice")
indicating whether the Company has elected to reset the interest rate (or the
spread or spread multiplier used to calculate such interest rate, if
applicable), and if so (i) such new interest rate (or such new spread or spread
multiplier, if applicable) and (ii) the provisions, if any, for redemption
during the period from such Optional Reset Date to the next Optional Reset Date
or if there is no such next Optional Reset Date, to the Stated Maturity Date of
such Security (each such period a "Subsequent Interest Period"), including the
date or dates on which or the period or periods during which and the price or
prices at which such redemption may occur during the Subsequent Interest Period.

         Notwithstanding the foregoing, not later than 20 days prior to the
Optional Reset Date, the Company may, at its option, revoke the interest rate
(or the spread or spread multiplier used to calculate such interest rate, if
applicable) provided for in the Reset Notice and establish an interest rate (or
a spread or spread multiplier used to calculate such interest rate, if
applicable) that is higher than the interest rate (or the spread or spread
multiplier, if applicable) provided for in the Reset Notice, for the Subsequent
Interest Period by causing the Trustee to transmit, in the manner provided for
in Section 106, notice of such higher interest rate (or such higher spread or
spread multiplier, if applicable) to the Holder of such Security.  Such notice
shall be irrevocable.  All Securities with respect to which the interest rate
(or the spread or spread multiplier used to calculate such interest rate, if
applicable) is reset on an Optional Reset Date, and with respect to which the
Holders of such Securities have not tendered such Securities for repayment (or
have validly revoked any such tender) 

<PAGE>

                                48


pursuant to the next succeeding paragraph, will bear such higher interest rate
(or such higher spread or spread multiplier, if applicable).

         The Holder of any such Security will have the option to elect
repayment by the Company of the principal of such Security on each Optional
Reset Date at a price equal to the principal amount thereof plus interest
accrued to such Optional Reset Date.  In order to obtain repayment on an
Optional Reset Date, the Holder must follow the procedures set forth in
Article Fourteen for repayment at the option of Holders except that the period
for delivery or notification to the Trustee shall be at least 25 but not more
than 35 days prior to such Optional Reset Date and except that, if the Holder
has tendered any Security for repayment pursuant to the Reset Notice, the Holder
may, by written notice to the Trustee, revoke such tender or repayment until the
close of business on the tenth day before such Optional Reset Date.

         Subject to the foregoing provisions of this Section and Section 306,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         SECTION 309.  OPTIONAL EXTENSION OF STATED MATURITY.

         The provisions of this Section 309 may be made applicable to any
series of Securities pursuant to Section 301 (with such modifications, additions
or substitutions as may be specified pursuant to such Section 301).  The Stated
Maturity of any Security of such series may be extended at the option of the
Company for the period or periods specified on the face of such Security (each
an "Extension Period") up to but not beyond the date (the "Final Maturity") set
forth on the face of such Security.  The Company may exercise such option with
respect to any Security by notifying the Trustee of such exercise at least 50
but not more than 60 days prior to the Stated Maturity of such Security in
effect prior to the exercise of such option (the "Original Stated Maturity"). 
If the Company exercises such option, the Trustee shall transmit, in the manner
provided for in Section 106, to the Holder of such Security not later than 40
days prior to the Original Stated Maturity a notice (the "Extension Notice")
indicating (i) the election of the Company to extend the Stated Maturity,
(ii) the new Stated Maturity, (iii) the interest rate, if any, applicable to the
Extension Period and (iv) the provisions, if any, for redemption during such
Extension Period.  Upon the Trustee's transmittal of the Extension Notice, the
Stated Maturity of such Security shall be extended automatically and, except as
modified by the Extension Notice and as described in the next paragraph, such
Security will have the same terms as prior to the transmittal of such Extension
Notice.

         Notwithstanding the foregoing, not later than 20 days before the
Original Stated Maturity of such Security, the Company may, at its option,
revoke the interest rate 

<PAGE>

                                49


provided for in the Extension Notice and establish a higher interest rate for
the Extension Period by causing the Trustee to transmit, in the manner provided
for in Section 106, notice of such higher interest rate to the Holder of such
Security.  Such notice shall be irrevocable.  All Securities with respect to
which the Stated Maturity is extended will bear such higher interest rate.

         If the Company extends the Maturity of any Security, the Holder will
have the option to elect repayment of such Security by the Company on the
Original Stated Maturity at a price equal to the principal amount thereof, plus
interest accrued to such date.  In order to obtain repayment on the Original
Stated Maturity once the Company has extended the Maturity thereof, the Holder
must follow the procedures set forth in Article Fourteen for repayment at the
option of Holders, except that the period for delivery or notification to the
Trustee shall be at least 25 but not more than 35 days prior to the Original
Stated Maturity and except that, if the Holder has tendered any Security for
repayment pursuant to an Extension Notice, the Holder may by written notice to
the Trustee revoke such tender for repayment until the close of business on the
tenth day before the Original Stated Maturity.

         SECTION 310.  PERSONS DEEMED OWNERS.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Registered Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 306 and 308)
interest, if any, on such Security and for all other purposes whatsoever,
whether or not such Security be overdue, and none of the Company, the Trustee or
any agent of the Company or the Trustee shall be affected by notice to the
contrary.

         Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Company, the Trustee and any agent of the Company
or the Trustee may treat the bearer of any Bearer Security and the bearer of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupons be overdue, and none of the
Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

<PAGE>

                                50


         Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company or the Trustee, from giving effect to any written certification, proxy
or other authorization furnished by any depositary, as a Holder, with respect to
such Global Security or impair, as between such depositary and owners of
beneficial interests in such Global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such Global Security.

         SECTION 311.  CANCELLATION.

         All Securities and coupons surrendered for payment, redemption,
repayment at the option of the Holder, registration of transfer or exchange or
for credit against any current or future sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee. 
All Securities and coupons so delivered to the Trustee shall be promptly
cancelled by it.  The Company may at any time deliver to the Trustee for
cancellation any Securities previously authenticated and delivered hereunder
which the Company may have acquired in any manner whatsoever, and may deliver to
the Trustee (or to any other Person for delivery to the Trustee) for
cancellation any Securities previously authenticated hereunder which the Company
has not issued and sold, and all Securities so delivered shall be promptly
cancelled by the Trustee.  If the Company shall so acquire any of the
Securities, however, such acquisition shall not operate as a redemption or
satisfaction of the indebtedness represented by such Securities unless and until
the same are surrendered to the Trustee for cancellation.  No Securities shall
be authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture.  All
cancelled Securities held by the Trustee shall be disposed of by the Trustee in
accordance with its customary procedures, unless by Company Order the Company
shall direct that cancelled Securities be returned to it.

         SECTION 312.  COMPUTATION OF INTEREST.

         Except as otherwise specified as contemplated by Section 301 with
respect to any Securities, interest, if any, on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months.

         SECTION 313.  CURRENCY AND MANNER OF PAYMENTS IN RESPECT OF
SECURITIES.

         (a)  With respect to Registered Securities of any series not
permitting the election provided for in paragraph (b) below or the Holders of
which have not made the election provided for in paragraph (b) below, and with
respect to Bearer Securities of any series, except as provided in paragraph (d)
below, payment of the principal of (and premium, if any) and interest, if any,
on any Registered or Bearer Security of such series will be made in the Currency
in which such Registered Security or Bearer Security, as the case may be, is 

<PAGE>

                                51


payable.  The provisions of this Section 313 may be modified or superseded with
respect to any Securities pursuant to Section 301.

         (b)  It may be provided pursuant to Section 301 with respect to
Registered Securities of any series that Holders shall have the option, subject
to paragraphs (d) and (e) below, to receive payments of principal of (or
premium, if any) or interest, if any, on such Registered Securities in any of
the Currencies which may be designated for such election by delivering to the
Trustee a written election with signature guarantees and in the applicable form
established pursuant to Section 301, not later than the close of business on the
Election Date immediately preceding the applicable payment date.  If a Holder so
elects to receive such payments in any such Currency, such election will remain
in effect for such Holder or any transferee of such Holder until changed by such
Holder or such transferee by written notice to the Trustee (but any such change
must be made not later than the close of business on the Election Date
immediately preceding the next payment date to be effective for the payment to
be made on such payment date and no such change of election may be made with
respect to payments to be made on any Registered Security of such series with
respect to which an Event of Default has occurred or with respect to which the
Company has deposited funds pursuant to Article Four or Fifteen or with respect
to which a notice of redemption has been given by the Company or a notice of
option to elect repayment has been sent by such Holder or such transferee).  Any
Holder of any such Registered Security who shall not have delivered any such
election to the Trustee not later than the close of business on the applicable
Election Date will be paid the amount due on the applicable payment date in the
relevant Currency as provided in Section 313(a).  The Trustee shall notify the
Exchange Rate Agent as soon as practicable after the Election Date of the
aggregate principal amount of Registered Securities for which Holders have made
such written election.

         (c)  Unless otherwise specified pursuant to Section 301, if the
election referred to in paragraph (b) above has been provided for pursuant to
Section 301, then, unless otherwise specified pursuant to Section 301, not later
than the fourth Business Day after the Election Date for each payment date for
Registered Securities of any series, the Exchange Rate Agent will deliver to the
Company a written notice specifying, in the Currency in which Registered
Securities of such series are payable, the respective aggregate amounts of
principal of (and premium, if any) and interest, if any, on the Registered
Securities to be paid on such payment date, specifying the amounts in such
Currency so payable in respect of the Registered Securities as to which the
Holders of Registered Securities of such series shall have elected to be paid in
another Currency as provided in paragraph (b) above.  If the election referred
to in paragraph (b) above has been provided for pursuant to Section 301 and if
at least one Holder has made such election, then, unless otherwise specified
pursuant to Section 301, on the second Business Day preceding such payment date
the Company will deliver to the Trustee for such series of Registered Securities
an Exchange Rate Officers' Certificate in respect of the Dollar or Foreign
Currency payments to be made on such payment date.  Unless otherwise specified
pursuant to 

<PAGE>

                                52


Section 301, the Dollar or Foreign Currency amount receivable by Holders of
Registered Securities who have elected payment in a Currency as provided in
paragraph (b) above shall be determined by the Company on the basis of the
applicable Market Exchange Rate in effect on the third Business Day (the
"Valuation Date") immediately preceding each payment date, and such
determination shall be conclusive and binding for all purposes, absent manifest
error.

         (d)  If a Conversion Event occurs with respect to a Foreign Currency
in which any of the Securities are denominated or payable other than pursuant to
an election provided for pursuant to paragraph (b) above or pursuant to the
terms of Section 301, then with respect to each date for the payment of
principal of (and premium, if any) and interest, if any, on the applicable
Securities denominated or payable in such Foreign Currency occurring after the
last date on which such Foreign Currency was used (the "Conversion Date"), the
Dollar shall be the Currency of payment for use on each such payment date. 
Unless otherwise specified pursuant to Section 301, the Dollar amount to be paid
by the Company to the Trustee and by the Trustee or any Paying Agent to the
Holders of such Securities with respect to such payment date shall be, in the
case of a Foreign Currency other than a currency unit, the Dollar Equivalent of
the Foreign Currency or, in the case of a currency unit, the Dollar Equivalent
of the Currency Unit, in each case as determined by the Exchange Rate Agent in
the manner provided in paragraph (f) or (g) below.

         (e)  Unless otherwise specified pursuant to Section 301, if the Holder
of a Registered Security denominated in any Currency shall have elected to be
paid in another Currency as provided in paragraph (b) above, and a Conversion
Event occurs with respect to such elected Currency, such Holder shall receive
payment in the Currency in which payment would have been made in the absence of
such election; and if a Conversion Event occurs with respect to the Currency in
which payment would have been made in the absence of such election, such Holder
shall receive payment in Dollars as provided in paragraph (d) above or as
otherwise provided pursuant to Section 301.

         (f)  The "Dollar Equivalent of the Foreign Currency" shall be
determined by the Exchange Rate Agent and shall be obtained for each subsequent
payment date by converting the specified Foreign Currency into Dollars at the
Market Exchange Rate on the Conversion Date.

         (g)  The "Dollar Equivalent of the Currency Unit" shall be determined
as specified pursuant to Section 301.  "Election Date" shall mean the date for
any series of Registered Securities as specified pursuant to clause (11) of
Section 301 by which the written election referred to in paragraph (b) above may
be made.

         All decisions and determinations of the Exchange Rate Agent regarding
the Dollar Equivalent of the Foreign Currency, the Dollar Equivalent of the
Currency Unit, the 

<PAGE>

                                53


Market Exchange Rate and changes in the Specified Amounts as specified above
shall be in its sole discretion and shall, in the absence of manifest error, be
conclusive for all purposes and irrevocably binding upon the Company, the
Trustee and all Holders of such Securities denominated or payable in the
relevant Currency.  The Exchange Rate Agent shall promptly give written notice
to the Company and the Trustee of any such decision or determination.

         Except as otherwise provided pursuant to Section 301, in the event
that the Company determines in good faith that a Conversion Event has occurred
with respect to a Foreign Currency, the Company will immediately give written
notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee
will promptly thereafter give notice in the manner provided for in Section 106
to the affected Holders) specifying the Conversion Date.  Except as otherwise
provided pursuant to Section 301, in the event the Company so determines that a
Conversion Event has occurred with respect to any currency unit in which
Securities are denominated or payable, the Company will immediately give written
notice thereof to the Trustee and to the Exchange Rate Agent (and the Trustee
will promptly thereafter give notice in the manner provided for in Section 106
to the affected Holders) specifying the Conversion Date and the Specified Amount
of each Component Currency on the Conversion Date.  In the event the Company
determines in good faith that any subsequent change in any Component Currency as
set forth in the definition of Specified Amount above has occurred, the Company
will similarly give written notice to the Trustee and the Exchange Rate Agent.

         The Trustee shall be fully justified and protected in relying and
acting upon information received by it from the Company and the Exchange Rate
Agent and shall not otherwise have any duty or obligation to determine the
accuracy or validity of such information independent of the Company or the
Exchange Rate Agent.

         SECTION 314.  APPOINTMENT AND RESIGNATION OF SUCCESSOR EXCHANGE RATE
AGENT.

         (a)  Unless otherwise specified pursuant to Section 301, if and so
long as the Securities of any series (i) are denominated in a Currency other
than Dollars or (ii) may be payable in a Currency other than Dollars, or so long
as it is required under any other provision of this Indenture, then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one Exchange Rate Agent.  The Company will cause the Exchange Rate
Agent to make the necessary foreign exchange determinations at the time and in
the manner specified pursuant to Section 301 for the purpose of determining the
applicable rate of exchange and, if applicable, for the purpose of converting
the issued Currency into the applicable payment Currency for the payment of
principal (and premium, if any) and interest, if any, pursuant to Section 313.

<PAGE>

                                54


         (b)  No resignation of the Exchange Rate Agent and no appointment of a
successor Exchange Rate Agent pursuant to this Section shall become effective
until the acceptance of appointment by the successor Exchange Rate Agent as
evidenced by a written instrument delivered to the Company and the Trustee.

         (c)  If the Exchange Rate Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of the Exchange
Rate Agent for any cause with respect to the Securities of one or more series,
the Company, by or pursuant to a Board Resolution, shall promptly appoint a
successor Exchange Rate Agent or Exchange Rate Agents with respect to the
Securities of that or those series (it being understood that any such successor
Exchange Rate Agent may be appointed with respect to the Securities of one or
more or all of such series and that, unless otherwise specified pursuant to
Section 301, at any time there shall only be one Exchange Rate Agent with
respect to the Securities of any particular series that are originally issued by
the Company on the same date and that are initially denominated and/or payable
in the same Currency).

         SECTION 315.  CUSIP NUMBERS.

         The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use) in addition to serial numbers, and, if so, the Trustee shall
use such "CUSIP" numbers in addition to serial numbers in notices of repurchase
as a convenience to Holders; PROVIDED that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a repurchase and that
reliance may be placed only on the serial or other identification numbers
printed on the Securities, and any such repurchase shall not be affected by any
defect in or omission of such "CUSIP" numbers.  The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

                    SATISFACTION AND DISCHARGE

         SECTION 401.  SATISFACTION AND DISCHARGE OF INDENTURE.

         This Indenture shall, upon Company Request, cease to be of further
effect with respect to any series of Securities specified in such Company
Request (except as to any surviving rights of registration of transfer or
exchange of Securities of such series expressly provided for herein or pursuant
hereto) and the Trustee, on demand of and at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture as to such series when

         delivered and all coupons, if any, appertaining thereto (other than
         (i) coupons appertaining to Bearer Securities surrendered for exchange
         for Registered Securities and maturing after such exchange, whose
         surrender is not required or has been waived as provided in
         Section 306, (ii) Securities and coupons of such series which have
         been destroyed, lost or stolen and which have been replaced or paid as
         provided in Section 307, (iii) coupons appertaining to Securities

         theretofore been deposited in trust with the Trustee or any Paying
         Agent or segregated and held in trust by the Company and thereafter
         repaid to the Company, as provided in Section 1003) have been
         delivered to the Trustee for cancellation; or

              (B)  all Securities of such series and, in the case of (i) or
         (ii) below, any coupons appertaining thereto not theretofore delivered
         to the Trustee for cancellation

                   (i)  have become due and payable, or

                   (ii) will become due and payable at their Stated Maturity

                   (iii)     if redeemable at the option of the Company, are to
                 be called for redemption within one year under arrangements
                 satisfactory to the Trustee for the giving of notice of
                 redemption by the Trustee in the name, and at the expense, of 
                 the Company,

         and the Company, in the case of (i), (ii) or (iii) above, has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust for such purpose an amount in the Currency in
         which the Securities of such series are payable, sufficient to pay and
         discharge the entire indebtedness on such Securities not theretofore
         delivered to the Trustee for cancellation, for principal (and premium,
         if any) and interest, if any, to the date of such deposit (in the case
         of Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

         (2)  the Company has paid or caused to be paid all other sums payable
    hereunder by the Company; and

<PAGE>

                                56


         (3)  the Company has delivered to the Trustee an Officers' Certificate
    and an Opinion of Counsel, each stating that all conditions precedent
    herein provided for relating to the satisfaction and discharge of this
    Indenture as to such series have been complied with.

         Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 606, the obligations of
the Trustee to any Authenticating Agent under Section 612 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of Subsection (1)
of this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

         SECTION 402.  APPLICATION OF TRUST MONEY.

         Subject to the provisions of the last paragraph of Section 1003, all
money deposited with the Trustee pursuant to Section 401 shall be held in trust
and applied by it, in accordance with the provisions of the Securities, the
coupons and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest, if any, for whose payment such money has been
deposited with the Trustee.

                             REMEDIES

         SECTION 501.  EVENTS OF DEFAULT.

         "Event of Default", wherever used herein with respect to Securities of
any series, means any one of the following events:

         (1)  default in the payment of any interest on any Security of that
    series, or any related coupon, when such interest or coupon becomes due and
    payable, and continuance of such default for a period of 30 days, whether
    or not such payment shall be prohibited by the provisions of Article Twelve
    hereof; or

         (2)  default in the payment of the principal of (or premium, if any,
    on) any Security of that series at its Maturity, upon acceleration,
    redemption or otherwise, whether or not such payment shall be prohibited by
    the provisions of Article Twelve hereof; or

<PAGE>

                                57


         (3)  default in the deposit of any sinking fund payment, when and as
    due by the terms of the Securities of that series and Article Thirteen; or 

         (4)  the Company fails to comply with any of its other agreements or
    covenants in, or provisions applicable to, the Securities of that series or
    this Indenture, and the Default continues for the period and after the
    notice, if any, specified below; or 

         (5)  a default occurs under any mortgage, indenture or instrument
    under which there may be issued or by which there may be secured or
    evidenced any Indebtedness for money borrowed by the Company or one of its
    Restricted Subsidiaries (or the payment of which is guaranteed by the
    Company or one of its Restricted Subsidiaries), whether such Indebtedness
    or guarantee now exists or shall be created hereafter (but excluding any
    Indebtedness for the deferred purchase price of property or services owed
    to the Person providing such property or services as to which the Company
    or such Restricted Subsidiary is contesting its obligation to pay the same
    in good faith and by proper proceedings and for which the Company or such
    Restricted Subsidiary has established appropriate reserves), and (i) either
    (A) such event of default results from the failure to pay any such
    Indebtedness at final maturity or (B) as a result of such event of default
    the maturity of such Indebtedness has been accelerated prior to its
    expressed maturity and (ii) the principal amount of such Indebtedness
    equals $10,000,000 or more or, together with the principal amount of any
    such Indebtedness in default for failure to pay principal at maturity or
    the maturity of which has been so accelerated, aggregates $10,000,000 or
    more; or

         (6)  a final judgment or final judgments for the payment of money are
    entered by a court or courts of competent jurisdiction against the Company
    or any Restricted Subsidiary and either (i) an enforcement proceeding shall
    have been commenced by any creditor upon such judgment or (ii) such
    judgment remains undischarged and unbonded for a period (during which
    execution shall not be effectively stayed) of 60 days, PROVIDED that the
    aggregate of all such judgments exceeds $10,000,000; or

         (7)  the Company pursuant to or within the meaning of any Bankruptcy
    Law:

            (i)    commences a voluntary case or proceeding, 

            (ii)   consents to the entry of an order for relief against it
         in an involuntary case or proceeding,

<PAGE>

                                58


            (iii)  consents to the appointment of a Custodian of it or for
         all or substantially all of its property,

            (iv)   makes a general assignment for the benefit of its
         creditors, or

            (v)    admits in writing that it generally is unable to pay its
         debts as the same become due; or

         (8)  a court of competent jurisdiction enters an order or decree under
    any Bankruptcy Law that:

            (i)    is for relief against the Company in an involuntary case
         or proceeding,

            (ii)   appoints a Custodian of the Company or for all or
         substantially all of its property, or

            (iii)  orders the liquidation of the Company;

    and in each case the order or decree remains unstayed and in effect for 60
    days; or

         (9)  any other Event of Default provided with respect to Securities of
    that series.

         A Default under Section 501(4) is not an Event of Default with respect
to a series until the Trustee notifies the Company in writing, or the Holders of
at least 25% in principal amount of all Outstanding Securities of such series
notify the Company and the Trustee in writing, of the Default, and the Company
does not cure the Default within 60 days (30 days in the case of a Default under
Section 801 or 1004) after receipt of the notice.  The notice must specify the
Default, demand that it be remedied and state that the notice is a "Notice of
Default."  Such notice to the Company shall be given by the Trustee if so
requested in writing by the Holders of 25% of the principal amount of all the
Outstanding Securities of such series.


         SECTION 502.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

         If an Event of Default (other than an Event of Default specified in
Section 501(7) or 501(8)) with respect to the Securities of any series at the
time Outstanding occurs and is continuing, then in every such case the Trustee
or the Holders of at least 25% in principal amount of the Outstanding Securities
of such series, by written notice to the Company and the agents, if any, under
the Bank Credit Agreement (and to the Trustee if such notice is given by such
Holders), may, and the Trustee at the written request of such 

<PAGE>

                                59


Holders shall, declare all unpaid principal of (or, if the Securities of such
series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal amount as may be specified in the terms of that
series), premium, if any, and accrued interest on all the Outstanding Securities
of such series to be due and payable, as specified below.  Upon a declaration of
acceleration with respect to Securities of any series (or of all series, as the
case may be), such principal and accrued interest shall be due and payable upon
the first to occur of an acceleration under the Bank Credit Agreement or
10 days after receipt by the Company and the agents, if any, under the Bank
Credit Agreement of such written notice given hereunder.  If an Event of Default
specified in Section 501(7) or 501(8) with respect to the Company occurs, the
amounts described above with respect to the Outstanding Securities of all series
shall IPSO FACTO become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.  Upon payment
of such principal and interest, all of the Company's obligations under the
Securities of such Series and this Indenture, other than obligations under
Section 606, shall terminate.  

         The Holders of at least a majority in principal amount of the
Outstanding Securities of any series (or of all series, as the case may be), by
written notice to the Trustee, may rescind an acceleration and its consequences
if (i) all existing Events of Default, other than the non-payment of principal
of, premium, if any, or interest on the Outstanding Securities of such series
(or of all series, as the case may be) and any related coupons which have become
due solely because of the acceleration, have been cured or waived and (ii) the
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

         Notwithstanding the preceding paragraph, in the event of a declaration
of acceleration in respect of the Securities of any series because an Event of
Default specified in Section 501(5) shall have occurred and be continuing, such
declaration of acceleration shall be automatically annulled if the Indebtedness
that is the subject of such Event of Default has been discharged or the holders
thereof have rescinded their declaration of acceleration in respect of such
Indebtedness, and written notice of such discharge or rescission, as the case
may be, shall have been given to the Trustee by the Company and countersigned by
the holders of such Indebtedness or a trustee, fiduciary or agent for such
holders, within 30 days after such declaration of acceleration in respect of the
Securities of such series, and no other Event of Default has occurred during
such 30-day period which has not been cured or waived during such period.

         Notices by the Trustee to the agents under the Bank Credit Agreement
provided for herein shall be delivered or mailed to Toronto Dominion (Texas),
Inc., 909 Fannin Street, Suite 1700, Houston, Texas 77010, Attention:  Agency
Department; and to any other person who hereafter becomes an agent under the
Bank Credit Agreement, provided the Trustee has been notified by the Company or
the Banks of the names and mailing addresses of such persons.

         SECTION 503.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
TRUSTEE.

         The Company covenants that if

         (1)  default is made in the payment of any interest on any Security
    and any related coupon when such interest becomes due and payable and such
    default continues for a period of 30 days, or

         (2)  default is made in the payment of the principal of (or premium,
    if any, on) any Security at the Maturity thereof,

then the Company will, upon demand of the Trustee, pay to it for the benefit of
the Holders of such Securities and coupons, the whole amount then due and
payable on such Securities and coupons for principal (and premium, if any) and
interest, if any, and interest on any overdue principal (and premium, if any)
and on any overdue interest, at the rate or rates prescribed therefor in such
Securities, and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon such Securities, wherever
situated.

         If an Event of Default with respect to Securities of any series (or of
all series, as the case may be) occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of Securities of such series (or of all series, as the case may be)
under this Indenture by such appropriate judicial proceedings as the Trustee
shall deem most effectual to protect and enforce such rights.

         SECTION 504.  TRUSTEE MAY FILE PROOFS OF CLAIM.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any 

<PAGE>

                                61


demand on the Company for the payment of overdue principal, premium, if any, or
interest) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

         (i)  to file and prove a claim for the whole amount of principal (and
    premium, if any), or such portion of the principal amount of any series of
    Original Issue Discount Securities or Indexed Securities as may be
    specified in the terms of such series, and interest, if any, owing and
    unpaid in respect of the Securities and to file such other papers or
    documents as may be necessary or advisable in order to have the claims of
    the Trustee (including any claim for the reasonable compensation, expenses,
    disbursements and advances of the Trustee, its agents and counsel) and of
    the Holders allowed in such judicial proceeding, and

         (ii) to collect and receive any moneys or other property payable or
    deliverable on any such claims and to distribute the same; and any
    custodian, receiver, assignee, trustee, liquidator, sequestrator or other
    similar official in any such judicial proceeding is hereby authorized by
    each Holder to make such payments to the Trustee and, in the event that the
    Trustee shall consent to the making of such payments directly to the
    Holders, to pay to the Trustee any amount due it for the reasonable
    compensation, expenses, disbursements and advances of the Trustee, its
    agents and counsel, and any other amounts due the Trustee under
    Section 606.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any proposal,
plan of reorganization, arrangement, adjustment or composition or other similar
arrangement affecting the Securities or the rights of any Holder thereof or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

         SECTION 505.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF
SECURITIES.

         All rights of action and claims under this Indenture or the Securities
or coupons may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or coupons or the production thereof in any proceeding
relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name and as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.

         SECTION 506.  APPLICATION OF MONEY COLLECTED.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, if any, upon presentation of the Securities or coupons, or
both, as the case may be, and the notation thereon of the payment if only
partially paid and upon surrender thereof if fully paid:

         FIRST:  To the payment of all amounts due the Trustee under
    Section 606;

         SECOND:  To the payment of the amounts then due and unpaid for
    principal of (and premium, if any) and interest, if any, on the Securities
    and coupons in respect of which or for the benefit of which such money has
    been collected, ratably, without preference or priority of any kind,
    according to the amounts due and payable on such Securities and coupons for
    principal (and premium, if any) and interest, if any, respectively; and

         THIRD:  The balance, if any, to the Company.

         SECTION 507.  LIMITATION ON SUITS.

         No Holder of any Security of any series or any related coupons shall
have any right to institute any proceeding, judicial or otherwise, with respect
to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless 

         (1)  such Holder has previously given written notice to the Trustee of
    a continuing Event of Default with respect to the Securities of that
    series;

         (2)  the Holders of not less than 25% in principal amount of the
    Outstanding Securities of that series in the case of any Event of Default
    described in clause (1), (2), (3), (4), (5), (6) or (9) of Section 501, or,
    in the case of any Event of Default described in clause (7) or (8) of
    Section 501, the Holders of not less than 25% in principal amount of all
    Outstanding Securities, shall have made written request to the Trustee to
    institute proceedings in respect of such Event of Default in its own name
    as Trustee hereunder;

         (3)  such Holder or Holders have offered to the Trustee reasonable
    indemnity against the costs, expenses and liabilities to be incurred in
    compliance with such request;

         (4)  the Trustee for 60 days after its receipt of such notice, request
    and offer of indemnity has failed to institute any such proceeding; and

<PAGE>

                                63


         (5)  no direction inconsistent with such written request has been
    given to the Trustee during such 60-day period by the Holders of a majority
    or more in principal amount of the Outstanding Securities of that series in
    the case of any Event of Default described in clause (1), (2), (3), (4),
    (5), (6) or (9) of Section 501, or, in the case of any Event of Default
    described in clause (7) or (8) of Section 501, by the Holders of a majority
    or more in principal amount of all Outstanding Securities;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Securities of the same series, in the case of any Event of Default
described in clause (1), (2), (3), (4), (5), (6) or (9) of Section 501, or of
Holders of all Securities in the case of any Event of Default described in
clause (7) or (8) of Section 501, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all Holders of Securities of the same series, in the case of any
Event of Default described in clause (1), (2), (3), (4), (5), (6) or (9) of
Section 501, or of Holders of all Securities in the case of any Event of Default
described in clause (7) or (8) of Section 501.

         SECTION 508.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL,
PREMIUM AND INTEREST.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 308) interest, if any, on, such Security or payment of such coupon on
the respective Stated Maturities expressed in such Security or coupon (or, in
the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment, and such rights shall not be impaired without
the consent of such Holder.

         SECTION 509.  RESTORATION OF RIGHTS AND REMEDIES.

         If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case the Company, the
Trustee and the Holders shall, subject to any determination in such proceeding,
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                64


         SECTION 510.  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided in Section 307, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders of Securities or
coupons is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         SECTION 511.  DELAY OR OMISSION NOT WAIVER.

         No delay or omission of the Trustee or of any Holder of any Security
or coupon to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.

         SECTION 512.  CONTROL BY HOLDERS.

         With respect to the Securities of any series, the Holders of not less
than a majority in principal amount of the Outstanding Securities of such series
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee, PROVIDED that in each case

         (1)  such direction shall not be in conflict with any rule of law or
    with this Indenture or expose the Trustee to personal liability, and

         (2)  subject to the provisions of the TIA Section 315, the Trustee may
    take any other action deemed proper by the Trustee which is not
    inconsistent with such direction.

         SECTION 513.  WAIVER OF PAST DEFAULTS.

         Subject to Section 502, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all the Securities of such series waive any past Default or Event
of Default described in clause (1), (2), (3), (4), (5), (6) or (9) of
Section 501 (or, in the case of a Default or Event of Default  described in
clause (7) or (8) of Section 501, the Holders of not less than a majority in 


<PAGE>

                                65


principal amount of all Outstanding Securities may waive any such past Default
or Event of Default), and its consequences, except a Default or Event of
Default.

         (1)  in respect of the payment of the principal of (or premium, if
    any) or interest, if any, on any Security or any related coupon, or

         (2)  in respect of a covenant or provision hereof which under
    Article Nine cannot be modified or amended without the consent of the
    Holder of each Outstanding Security of such series affected.

         Upon any such waiver, such Default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

         SECTION 514.  UNDERTAKING FOR COSTS.

         All parties to this Indenture agree, and each Holder of Securities of
any series by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken, suffered or omitted by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities of any series, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on Securities of any series on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date); PROVIDED that neither this Section 514 nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company.

         SECTION 515.  WAIVER OF STAY OR EXTENSION LAWS.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the 

<PAGE>

                                66


execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.


                           ARTICLE SIX

                           THE TRUSTEE

         SECTION 601.  NOTICE OF DEFAULTS.

respect to the Securities of any series, the Trustee shall transmit by mail to
all Holders, as their names and addresses appear in the Security Register,
notice of such default hereunder known to the Trustee, unless such Default shall
have been cured or waived; PROVIDED, HOWEVER, that, except in the case of a
default in the payment of the principal of (or premium, if any) or interest, if
any, on any Security of such series or in the payment of any sinking fund
installment with respect to Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders of Securities of such series and any
related coupons; and PROVIDED FURTHER that in the case of any default or breach
of the character specified in Section 501(4) with respect to Securities of such
series, no such notice to Holders shall be given until at least 30 days after
the occurrence thereof.

         SECTION 602.  CERTAIN RIGHTS OF TRUSTEE.

         Subject to the provisions of TIA Sections 315(a) through 315(d):

    taking, suffering or omitting any action hereunder, the Trustee (unless
    other evidence be herein 

<PAGE>

                                67


    specifically prescribed) may, in the absence of bad faith on its part, rely
    upon an Officers' Certificate;

         (4)  the Trustee may consult with counsel of its selection and the
    advice of such counsel or any Opinion of Counsel shall be full and complete

    bond, debenture, note, other evidence of indebtedness or other paper or
    document, but the Trustee, in its discretion, may make such further inquiry
    or investigation into such facts or matters as it may see fit, and, if the
    Trustee shall determine to make such further inquiry or investigation, it
    shall be entitled to examine the books, records and premises of the
    Company, personally or by agent or attorney;

    perform any duties hereunder either directly or by or through agents or
    attorneys and the Trustee shall not be responsible for any misconduct or
    negligence on the part of any agent or attorney appointed with due care by
    it hereunder; and

         (8)  no provision of this Indenture shall require the Trustee to
    expend or risk its own funds or otherwise incur any financial liability in
    the performance of any of its duties hereunder, or in the exercise of any
    of its rights or powers if it shall have reasonable grounds for believing
    that repayment of such funds or adequate indemnity against such risk or
    liability is not reasonably assured to it.

         SECTION 603.  TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF
SECURITIES.

         The recitals contained herein and in the Securities, except for the

representations as to the validity or sufficiency 

<PAGE>

                                68


of this Indenture or of the Securities or coupons.  The Trustee shall not be
accountable for the use or application by the Company of Securities or the
proceeds thereof, except that the Trustee represents that it is duly authorized
to execute and deliver this Indenture, authenticate the Securities and perform
its obligations hereunder and that the statements to be made by it in a
Statement of Eligibility on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein.  Neither the Trustee
nor any Authenticating Agent shall be accountable for the use or application by

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law.  The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.

         SECTION 606.  COMPENSATION AND REIMBURSEMENT.

         The Company agrees:

         (1)  to pay to the Trustee from time to time such compensation as
    shall be agreed to in writing between the Company and the Trustee for all
    services rendered by it hereunder (which compensation shall not be limited
    by any provision of law in regard to the compensation of a trustee of an
    express trust);

         (2)  except as otherwise expressly provided herein, to reimburse the
    Trustee upon its request for all reasonable expenses, disbursements and
    advances incurred or made by the Trustee in accordance with any provision
    of this Indenture (including the reasonable compensation and the expenses
    and disbursements of its agents and counsel), except any such expense,
    disbursement or advance as may be attributable to its negligence or bad
    faith; and

<PAGE>

                                69


         (3)  to indemnify each of Trustee or any predecessor Trustee for, and
    to hold it harmless against, any and all loss, damage, claim, liability or
    expense including taxes (other than taxes based on the income of the
    Trustee) incurred without negligence or bad faith on its part, arising out
    of or in connection with the acceptance or administration of this trust,
    including the costs and expenses of defending itself against any claim or
    liability in connection with the exercise or performance of any of its
    powers or duties hereunder.

         As security for the performance of the obligations of the Company
under this Section 606, the Trustee shall have a lien prior to the Securities
upon all property and funds held or collected by the Trustee as such, except
funds held in trust for the payment of principal of (or premium, if any) or
interest, if any, on particular Securities or any coupons.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(5) or (6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services will be intended to constitute expenses of
administration under any Bankruptcy Law.

         SECTION 608.  CORPORATE TRUSTEE REQUIRED; ELIGIBILITY; CONFLICTING
INTERESTS.

         There shall at all times be a Trustee hereunder qualified or to be
qualified under TIA Section 310(a)(1) and which, to the extent there is such an

                                70


report of condition so published.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 608, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

         SECTION 609.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

         (a)  No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 610.

         (b)  The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company.  If the
instrument of acceptance by a successor Trustee required by Section 609 shall
not have been delivered to the Trustee within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee with respect to the
Securities of such series.

         (c)  The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the
Trustee and the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of removal, the removed Trustee may petition a court of competent
jurisdiction for the appointment of a successor Trustee.

         (d)  If at any time:

         (1)  the Trustee shall fail to comply with the provisions of TIA
    Section 310(b) after written request therefor by the Company or by any
    Holder who has been a bona fide Holder of a Security for at least six
    months, or 

         (2)  the Trustee shall cease to be eligible under Section 608 and
    shall fail to resign after written request therefor by the Company or by
    any Holder who has been a bona fide Holder of a Security for at least six
    months, or 

         (3)  the Trustee shall become incapable of acting or shall be adjudged
    a bankrupt or insolvent or a receiver of the Trustee or of its property
    shall be appointed or any public officer shall take charge or control of
    the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee with respect to all Securities, or (ii) subject to TIA Section 514, the
Holder of any Security who has been a bona fide Holder of a Security for at
least six months may, on behalf of 

<PAGE>

                                71


himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

         (e)  If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause, with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee or Trustees with respect
to the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series).  If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with Section 610, become the successor Trustee
with respect to the Securities of such series and to that extent supersede the
successor Trustee appointed by the Company.  If no successor Trustee with
respect to the Securities of any series shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security of such
series for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (f)  The Company shall give notice of each resignation and each
removal of the Trustee with respect to the Securities of any series and each
appointment of a successor Trustee with respect to the Securities of any series
to the Holders of Securities of such series in the manner provided for in
Section 106.  Each notice shall include the name of the successor Trustee with
respect to the Securities of such series and the address of its Corporate Trust
Office.

         SECTION 610.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a)  Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; PROVIDED, HOWEVER, that the
retiring Trustee shall continue to be entitled to the benefit of Section 606;
but, on the request of the Company or the successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly 

<PAGE>

                                72


assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.

         (b)  In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates,
(2) if the retiring Trustee is not retiring with respect to all Securities,
shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates; but, on request of the Company or any successor Trustee, such
retiring Trustee shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder with
respect to the Securities of that or those series to which the appointment of
such successor Trustee relates.  Whenever there is a successor Trustee with
respect to one or more (but less than all) series of securities issued pursuant
to this Indenture, the terms "Indenture" and "Securities" shall have the
meanings specified in the provisos to the respective definitions of those terms
in Section 101 which contemplate such situation.

         (c)  Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

         (d)  No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

         SECTION 611.  MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

         Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.  In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities. 
In case any of the Securities shall not have been authenticated by such
predecessor Trustee, any successor Trustee may authenticate such Securities
either in the name of any predecessor hereunder or in the name of the successor
Trustee.  In all such cases such certificates shall have the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee; PROVIDED, HOWEVER, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Securities in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

         SECTION 612.  APPOINTMENT OF AUTHENTICATING AGENT.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series and the Trustee shall give written notice
of such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106.  Securities so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Any such appointment shall be evidenced
by an instrument in writing signed by a Responsible Officer of the Trustee, and
a copy of such instrument shall be promptly furnished to the Company.  Wherever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee's certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent.  Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any state thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination
by 

<PAGE>

                                74


federal or state authority.  If such corporation publishes reports of condition
at least annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an
Authenticating Agent, PROVIDED such corporation shall be otherwise eligible
under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give written notice of
such appointment to all Holders of Securities of the series with respect to
which such Authenticating Agent will serve, in the manner provided for in
Section 106.  Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible under the provisions of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:

         Dated:  ____________________

         This is one of the Securities of the series designated therein
    referred to in the within-mentioned Indenture.

provisions of the Trust Indenture Act regarding the collection of claims against

    the Stated Maturity thereof (or, in the case of redemption or repayment at
    the option of the Holder, on or after the Redemption Date or Repayment
    Date, as the case may be), or adversely affect any right to convert or
    exchange any Security as may be provided pursuant to Section 301 herein, or

         (2)  reduce the percentage in principal amount of the Outstanding
    Securities of such series the consent of whose Holders is required for any
    such supplemental indenture, or the consent of whose Holders is required
    for any waiver (of compliance with certain provisions of this Indenture
    which affect such series or certain defaults applicable to such series
    hereunder and their consequences) provided for in this Indenture, or reduce
    the requirements of Section 1604 for quorum or voting with respect to
    Securities of such series, or

         (3)  modify any of the provisions of this Indenture relating to the
    subordination of the Securities of any series in a manner adverse to the
    Holders of such Outstanding Securities, or

         (4)  modify any of the provisions of this Section 902, Section 513 or
    Section 1014, except to increase any such percentage or to provide that
    certain other provisions of this Indenture which affect such series cannot
    be modified or waived without the consent of the Holder of each Outstanding
    Security affected thereby of such series.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.  Any such
supplemental indenture adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture, or modifying in any manner
the rights of the Holders of Securities of such series, shall not affect the
rights under this Indenture of the Holders of Securities of any other series.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

         SECTION 903.  EXECUTION OF SUPPLEMENTAL INDENTURES.

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to TIA Section 315(a) through 315(d) and Section 602 hereof) shall
be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such supplemental indenture is authorized or permitted by this
Indenture.  The Trustee may, but shall not be obligated to, enter into any such
supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

         SECTION 904.  EFFECT OF SUPPLEMENTAL INDENTURES.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

         SECTION 905.  CONFORMITY WITH TRUST INDENTURE ACT.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 906.  REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

         Securities of any series authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article may, and shall
if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture.  If the Company shall
so determine, new Securities of any series so modified as to conform, in the
opinion of the Trustee and the Company, to any such supplemental indenture may
be prepared and executed by the Company and authenticated and delivered by the
Trustee in exchange for Outstanding Securities of such series.

         SECTION 907.  NOTICE OF SUPPLEMENTAL INDENTURES.

         Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of Section 902, the Company
shall give notice thereof to the Holders of each Outstanding Security affected,
in the manner provided for in Section 106, setting forth in general terms the
substance of such supplemental indenture.


                           ARTICLE TEN

                            COVENANTS

         SECTION 1001.  PAYMENT OF PRINCIPAL, PREMIUM, IF ANY, AND INTEREST.

         The Company covenants and agrees for the benefit of the Holders of
each series of Securities and any related coupons that it will duly and
punctually pay the principal of (and premium, if any) and interest, if any, on
the Securities of that series in accordance with the terms of the Securities,
any coupons appertaining thereto and this Indenture.  Unless otherwise specified
as contemplated by Section 301 with respect to any series of Securities, any
interest installments due on Bearer Securities on or before Maturity shall be
payable only upon presentation and surrender of the several coupons for such
interest installments as are evidenced thereby as they severally mature.

         SECTION 1002.  MAINTENANCE OF OFFICE OR AGENCY.

         If the Securities of a series are issuable only as Registered
Securities, the Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange, where Securities of that series that
are convertible or exchangeable may be surrendered for conversion or exchange,
as applicable and where notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be served.

         If Securities of a series are issuable as Bearer Securities, the
Company will maintain (A) in The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where Securities of that series that are convertible or exchangeable
may be surrendered for conversion or exchange, as applicable, where notices and
demands to or upon the Company in respect of the Securities of that series and
this Indenture may be served and where Bearer Securities of that series and

<PAGE>

                                83


be presented or surrendered for payment in the circumstances described in the
following paragraph (and not otherwise) (B) subject to any laws or regulations
applicable thereto, in a Place of Payment for that series which is located
outside the United States, an office or agency where Securities of that series
and related coupons may be presented and surrendered for payment; PROVIDED,
HOWEVER, that, if the Securities of that series are listed on any stock exchange
located outside the United States and such stock exchange shall so require, the
Company will maintain a Paying Agent for the Securities of that series in any
required city located outside the United States so long as the Securities of
that series are listed on such exchange, and (C) subject to any laws or
regulations applicable thereto, in a Place of Payment for that series located
outside the United States an office or agency where any Registered Securities of
that series may be surrendered for registration of transfer, where Securities of
that series may be surrendered for exchange, where Securities of that series
that are convertible and exchangeable may be surrendered for conversion or
exchange, as applicable and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served.

         The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency.  If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, except that Bearer Securities of any series and the
related coupons may be presented and surrendered for payment at the offices
specified in the Security, in London, and the Company hereby appoints the same
as its agents to receive such respective presentations, surrenders, notices and
demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; PROVIDED, HOWEVER, that, if
the Securities of a series are payable in Dollars, payment of principal of (and
premium, if any) and interest, if any, on any Bearer Security shall be made at
the office of the Company's Paying Agent in The City of New York, if (but only
if) payment in Dollars of the full amount of such principal, premium or
interest, as the case may be, at all offices or agencies outside the United
States maintained for such purpose by the Company in accordance with this
Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
any such designation; PROVIDED, HOWEVER, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth 

<PAGE>

                                84


above for Securities of any series for such purposes.  The Company will give
prompt written notice to the Trustee of any such designation or rescission and
of any change in the location of any such other office or agency.  Unless
otherwise specified with respect to any Securities as contemplated by
Section 301 with respect to a series of Securities, the Company hereby
designates as a Place of Payment for each series of Securities the office or
agency of the Company in the Borough of Manhattan, The City of New York, and
initially appoints the Trustee at its Corporate Trust Office as Paying Agent in
such city and as its agent to receive all such presentations, surrenders,
notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Currency other than Dollars or (ii) may be payable in a Currency other than
Dollars, or so long as it is required under any other provision of the
Indenture, then the Company will maintain with respect to each such series of
Securities, or as so required, at least one Exchange Rate Agent.

         SECTION 1003.  MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities and any related coupons, it will, on or
before each due date of the principal of (or premium, if any) or interest, if
any, on any of the Securities of that series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay the principal
of (or premium, if any) or interest, if any, on Securities of such series so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided and will promptly notify the Trustee of its action or
failure so to act.

         Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, prior to or on each due
date of the principal of (or premium, if any) or interest, if any, on any
Securities of that series, deposit with a Paying Agent a sum (in the Currency
described in the preceding paragraph) sufficient to pay the principal (or
premium, if any) or interest, if any, so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its action or failure so to act.

         The Company will cause each Paying Agent (other than the Trustee) for
any series of Securities to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent will:

<PAGE>

                                85


         (1)  hold all sums held by it for the payment of the principal of (and
    premium, if any) and interest, if any, on Securities of such series in
    trust for the benefit of the Persons entitled thereto until such sums shall
    be paid to such Persons or otherwise disposed of as herein provided;

         (2)  give the Trustee notice of any default by the Company (or any
    other obligor upon the Securities of such series) in the making of any
    payment of principal of (or premium, if any) or interest, if any, on the
    Securities of such series; and

         (3)  at any time during the continuance of any such default, upon the
    written request of the Trustee, forthwith pay to the Trustee all sums so
    held in trust by such Paying Agent.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
sums.

         Except as provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (or premium, if any) or interest, if
any, on any Security of any series, or any coupon appertaining thereto, and
remaining unclaimed for two years after such principal, premium or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security or coupon shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

         SECTION 1004.  CORPORATE EXISTENCE.

         Subject to Article Eight, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and that of each Restricted Subsidiary and the corporate rights
(charter and statutory), corporate licenses and corporate franchises of the
Company and its Restricted Subsidiaries, except where a failure to do so, singly
or in the aggregate, is not likely to have a materially adverse effect upon the
business, assets, financial condition or results of operations of the Company
and the Restricted Subsidiaries taken as a whole determined on a consolidated
basis in accordance with generally accepted accounting principles; PROVIDED that
the Company shall not be required to preserve any such existence (except of the
Company), right, license or franchise if the Board of Directors, or of the
Restricted Subsidiary concerned, shall determine that the preservation thereof
is no longer desirable in the conduct of the business of the Company or such
Restricted Subsidiary and that the loss thereof is not disadvantageous in any
material respect to the Holders.

         SECTION 1005.  PAYMENT OF TAXES AND OTHER CLAIMS.

         The Company shall pay or discharge or cause to be paid or discharged,
before the same shall become delinquent, (a) all material taxes, assessments and
governmental charges levied or imposed upon it or any Subsidiary or upon the
income, profits or property of the Company or any of its Subsidiaries and (b)
all material lawful claims for labor, materials and supplies, which, if unpaid,
might by law become a lien upon the property of the Company or any Restricted
Subsidiary; PROVIDED, HOWEVER, that the Company shall not be required to pay or
discharge or cause to be paid or discharged any such tax, assessment, charge or
claim whose amount, applicability or validity is being contested in good faith
by appropriate proceedings.

         SECTION 1006.  MAINTENANCE OF PROPERTIES.

         The Company shall cause all material properties owned by or leased to
it or any Restricted Subsidiary and necessary in the conduct of its business or
the business of such Restricted Subsidiary to be maintained and kept in normal
condition, repair and working order, ordinary wear and tear excepted; PROVIDED
that nothing in this Section shall prevent the Company or any Restricted
Subsidiary from discontinuing the use, operation or maintenance of any of such
properties, or disposing of any of them, if such discontinuance or disposal is,
in the judgment of the Board of Directors or the Restricted Subsidiary
concerned, or of any officer (or other agent employed by the Company or any
Restricted Subsidiary) of the Company or such Restricted Subsidiary having
managerial responsibility for any such property, desirable in the conduct of the
business of the Company or any Restricted Subsidiary of the Company and if such
discontinuance or disposal is not adverse in any material respect to the
Holders.

<PAGE>

                                87


         The Company shall provide or cause to be provided, for itself and any
Restricted Subsidiaries, insurance (including appropriate self-insurance)
against loss or damage of the kinds customarily insured against by corporations
similarly situated and owning like properties in the same general areas in which
the Company or such Restricted Subsidiaries operate.


         SECTION 1007.  LIMITATION ON INDEBTEDNESS.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, incur, create, issue, assume, guarantee or otherwise
become liable for, contingently or otherwise, or become responsible for the
payment of, contingently or otherwise, any Indebtedness (other than Indebtedness
between or among any of the Company and Restricted Subsidiaries) unless, after
giving effect thereto, the Cash Flow Ratio shall be less than or equal to 9 to
1.

         SECTION 1008.  LIMITATION ON SENIOR SUBORDINATED INDEBTEDNESS.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become liable for, contingently or otherwise, or become responsible for the
payment of, contingently or otherwise, any Indebtedness which is both (i) senior
in right of payment to the Securities of any series and (ii) expressly
subordinate in right of payment to any other Indebtedness of the Company. 
For purposes of this Section 1008, Indebtedness is deemed to be senior in right
of payment to the Securities of a series if it is not subordinate in right of
payment to Senior Indebtedness at least to the same extent as the Securities of
such series are subordinate to Senior Indebtedness.

         SECTION 1009.  LIMITATION ON RESTRICTED PAYMENTS.

         Except as otherwise provided in this Section 1009, the Company shall
not, and shall not permit any Restricted Subsidiary to, make any Restricted
Payment if (a) at the time of such proposed Restricted Payment, a Default or
Event of Default shall have occurred and be continuing or shall occur as a
consequence of such Restricted Payment or (b) immediately after giving effect to
such Restricted Payment, the aggregate of all Restricted Payments that shall
have been made on or after July 1, 1988 would exceed the sum of:

         (i)  $25,000,000, plus

         (ii) an amount equal to the difference between (A) the Cumulative Cash
    Flow Credit and (B) 1.2 multiplied by Cumulative Interest Expense.

<PAGE>

                                88


         For purposes of this Section 1009, the amount of any Restricted
Payment, if other than cash, shall be based upon fair market value as determined
by the Board of Directors, whose good faith determination shall be conclusive.

         The foregoing provisions of this Section 1009 shall not prevent (i) 
the payment of any dividend within 60 days after the date of declaration 
thereof, if at such date of declaration such payment complied with the 
provisions of this Section 1009; (ii) the retirement, redemption, purchase, 
defeasance or other acquisition of any shares of the Company's Capital Stock 
or warrants, rights or options to acquire Capital Stock of the Company, in 
exchange for, or out of the proceeds of a sale (within one year before or 180 
days after such retirement, redemption, purchase, defeasance or other 
acquisition) of, other shares of its Capital Stock or warrants, rights or 
options to acquire Capital Stock of the Company; and (iii) the redemption of, 
or payments of cash dividends on, the Company's 8% Series C Cumulative 
Preferred Stock (the "Series C Preferred Stock") outstanding on January 1, 
1997, which redemptions or dividends are provided for by the terms of the 
Series C Preferred Stock in effect on such date (or the redemption of or 
payment of cash dividends on any security of the Company issued in exchange 
for or upon the conversion of such Series C Preferred Stock; PROVIDED that 
the aggregate amount payable pursuant to the terms of such security is no 
greater than the aggregate amount payable pursuant to the terms of the Series 
C Preferred Stock).  For purposes of determining the aggregate permissible 
amount of Restricted Payments in accordance with clause (b) of the first 
paragraph of this Section 1009, all amounts expended pursuant to clauses (i) 
and (iii) of this paragraph shall be included and all amounts expended or 
received pursuant to clause (ii) of this paragraph shall be excluded; 
PROVIDED, HOWEVER, that amounts paid pursuant to clause (i) of this paragraph 
shall be included only to the extent that such amounts were not previously 
included in calculating Restricted Payments.

         For the purposes of this Section 1009, the net proceeds from the 
issuance of shares of Capital Stock of the Company upon conversion of 
Indebtedness shall be deemed to be an amount equal to (i) the accreted value 
of such Indebtedness on the date of such conversion and (ii) the additional 
consideration, if any, received by the Company upon such conversion thereof, 
less any cash payment on account of fractional shares (such consideration, if 
in property other than cash, to be determined by the Board of Directors, 
whose good faith determination shall be conclusive). If the Company makes a 
Restricted Payment which, at the time of the making of such Restricted 
Payment, would in the good faith determination of the Company be permitted 
under the requirements of this Section 1009, such Restricted Payment shall be 
deemed to have been made in compliance with this Section 1009 notwithstanding 
any subsequent adjustments made in good faith to the Company's financial 
statements affecting Cumulative Cash Flow Credit or Cumulative Interest 
Expense for any period.

         SECTION 1010.  LIMITATION ON INVESTMENTS IN UNRESTRICTED SUBSIDIARIES
AND AFFILIATES.

         The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, (i) make any Investment or (ii) allow any Restricted
Subsidiary to become an Unrestricted Subsidiary (a "redesignation of a
Restricted Subsidiary"), in each case unless (a) no Default or Event of Default
shall have occurred and be continuing or shall occur as a consequence of such
Investment or such redesignation of a Restricted Subsidiary and (b) after giving
effect thereto, the Cash Flow Ratio shall be less than or equal to 9 to 1.

         The foregoing provisions of this Section 1010 shall not prohibit (i)
any renewal or reclassification of any Investment existing on the date hereof or
(ii) trade credit extended on usual and customary terms in the ordinary course
of business.

         SECTION 1011.  TRANSACTIONS WITH AFFILIATES.

         The Company shall not, and shall not permit any of its Subsidiaries
to, sell, lease, transfer or otherwise dispose of any of its properties or
assets to or purchase any property or assets from, or enter into any contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, an Affiliate of the Company that is not a Subsidiary, having a value, or for
consideration having a value, in excess of $10,000,000 individually or in the
aggregate unless the Board of Directors shall make a good faith determination
that the terms of such transaction are, taken as a whole, no less favorable to
the Company or such subsidiary, as the case may be, than those which might be
available in a comparable transaction with an unrelated Person.  For purposes of
clarification, this Section 1011 shall not apply to any Restricted Payments
permitted by Section 1009.

         SECTION 1012.  PROVISION OF FINANCIAL STATEMENTS.

         (a)  The Company shall supply without cost to each Holder of the
Securities of any series, and file with the Trustee (if not otherwise filed with
the Trustee pursuant to Section 703) within 30 days after the Company is
required to file the same with the Commission, copies of the annual reports and
quarterly reports and of the information, documents and other reports which the
Company may be required to file with the Commission pursuant to Section 13(a),
13(c) or 15(d) of the Exchange Act.

         (b)  If the Company is not required to file with the Commission such
reports and other information referred to in Section 1012(a), the Company shall
furnish without cost to each Holder of the Securities and file with the Trustee
(i) within 140 days after the end of each fiscal year, annual reports containing
the information required to be contained in Items 1, 2, 3, 6, 7, 8 and 9 of Form
10-K promulgated under the Exchange Act, or substantially the same information
required to be contained in comparable items of 

<PAGE>

                                90


any successor form, and (ii) within 75 days after the end of each of the first
three fiscal quarters of each fiscal year, quarterly reports containing the
information required to be contained in Form 10-Q promulgated under the Exchange
Act, or substantially the same information required to be contained in any
successor form.

         SECTION 1013.  STATEMENT AS TO COMPLIANCE.

         The Company will deliver to the Trustee, within 120 days after the end
of each fiscal year ending after the date hereof, a brief certificate of its
principal executive officer, principal financial officer or principal accounting
officer stating whether, to such officer's knowledge, the Company is in
compliance with all covenants and conditions to be complied with by it under
this Indenture.  For purposes of this Section 1013, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

         SECTION 1014.  WAIVER OF CERTAIN COVENANTS.

         The Company may omit in any particular instance to comply with any
covenant or condition set forth in Sections 1007 through 1012 with respect to
Securities of any series if, before or after the time for such compliance, the
Holders of a majority in aggregate principal amount of all Outstanding
Securities of the series shall, by Act of such Holders, waive such compliance in
such instance or generally waive compliance with such covenant or condition, but
no such waiver shall extend to or affect such covenant or condition except to
the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any
such covenant or condition shall remain in full force and effect.

         SECTION 1102.  ELECTION TO REDEEM; NOTICE TO TRUSTEE.

         The election of the Company to redeem any Securities shall be
evidenced by or pursuant to a Board Resolution.  In case of any redemption at

the principal amount of Securities of such series to be redeemed and shall
deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Securities to be redeemed pursuant to Section 1103.  In
the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

         SECTION 1103.  SELECTION BY TRUSTEE OF SECURITIES TO BE REDEEMED.

         If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities of
such series not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions of the principal of Securities of such series; PROVIDED,
HOWEVER, that no such partial redemption shall reduce the portion of the
principal amount of a Security not redeemed to less than the minimum authorized
denomination for Securities of such series established pursuant to Section 301.

         The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

         For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 1104.  NOTICE OF REDEMPTION.

         Except as otherwise specified as contemplated by Section 301, notice
of redemption shall be given in the manner provided for in Section 106 not less
than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed.

         All notices of redemption shall identify the Securities (including
CUSIP number, if any) to be redeemed and shall state:

<PAGE>

                                92


         (1)  the Redemption Date,

         (2)  the Redemption Price and the amount of accrued interest to the
    Redemption Date payable as provided in Section 1106, if any,

         (3)  if less than all the Outstanding Securities of any series are to
    be redeemed, the identification (and, in the case of partial redemption,
    the principal amounts) of the particular Securities to be redeemed,

         (4)  in case any Security is to be redeemed in part only, the notice
    which relates to such Security shall state that on and after the Redemption
    Date, upon surrender of such Security, the holder will receive, without
    charge, a new Security or Securities of authorized denominations for the
    principal amount thereof remaining unredeemed,

         (5)  that on the Redemption Date, the Redemption Price and accrued
    interest, if any, to the Redemption Date payable as provided in
    Section 1106 will become due and payable upon each such Security, or the
    portion thereof, to be redeemed and, if applicable, that interest thereon
    will cease to accrue on and after said date,

         (6)  the Place or Places of Payment where such Securities, together in
    the case of Bearer Securities with all coupons appertaining thereto, if
    any, maturing after the Redemption Date, are to be surrendered for payment
    of the Redemption Price and accrued interest, if any,

         (7)  that the redemption is for a sinking fund, if such is the case,

         (8)  that, unless otherwise specified in such notice, Bearer
    Securities of any series, if any, surrendered for redemption must be
    accompanied by all coupons maturing subsequent to the Redemption Date or
    the amount of any such missing coupon or coupons will be deducted from the
    Redemption Price unless security or indemnity satisfactory to the Company,
    the Trustee and any Paying Agent is furnished, and

         (9)  if Bearer Securities of any series are to be redeemed and any
    Registered Securities of such series are not to be redeemed, and if such
    Bearer Securities may be exchanged for Registered Securities not subject to
    redemption on such Redemption Date pursuant to Section 306 or otherwise,
    the last date, as determined by the Company, on which such exchanges may be
    made.

<PAGE>

                                93


         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         SECTION 1105.  DEPOSIT OF REDEMPTION PRICE.

         Prior to any Redemption Date, the Company shall deposit with the
Trustee or with a Paying Agent (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money in the Currency in which the Securities of such series are payable (except
as otherwise specified pursuant to Section 301 for the Securities of such series
and except, if applicable, as provided in Sections 313(b), 313(d) and 313(e))
sufficient to pay the Redemption Price of, and accrued interest, if any, on, all
the Securities which are to be redeemed on that date.

         SECTION 1106.  SECURITIES PAYABLE ON REDEMPTION DATE.

         Notice of redemption having been given as aforesaid, the Securities so
to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified in the Currency in which the Securities of
such series are payable (except as otherwise specified pursuant to Section 301
for the Securities of such series and except, if applicable, as provided in
Sections 313(b), 313(d) and 313(e)) (together with accrued interest, if any, to
the Redemption Date), and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest, if any)
such Securities shall, if the same were interest-bearing, cease to bear interest
and the coupons for such interest appertaining to any Bearer Securities so to be
redeemed, except to the extent provided below, shall be void.  Upon surrender of
any such Security for redemption in accordance with said notice, together with
all coupons, if any, appertaining thereto maturing after the Redemption Date,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest, if any, to the Redemption Date; PROVIDED, HOWEVER, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and PROVIDED FURTHER
that installments of interest on Registered Securities whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 308.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the 

<PAGE>

                                94


Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made from the Redemption Price, such Holder shall be entitled to receive
the amount so deducted; PROVIDED, HOWEVER, that interest represented by coupons
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only upon presentation and surrender of those
coupons.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate of interest or
Yield to Maturity (in the case of Original Issue Discount Securities) set forth
in such Security.

         SECTION 1107.  SECURITIES REDEEMED IN PART.

         Any Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Thirteen) shall be surrendered at a
Place of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or such Holder's
attorney duly authorized in writing), and the Company shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of the same series, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.


                          ARTICLE TWELVE

                          SUBORDINATION

         SECTION 1201.  SECURITIES SUBORDINATED TO SENIOR INDEBTEDNESS.

         Except as otherwise specified as contemplated by Section 301, the
following provisions shall apply to Securities of each series.

         The Company, for itself and its successors, and each Holder of a
Security of any series or of any coupon appertaining thereto, by his acceptance
of Securities of any series, agrees, that the payment of all amounts due in
respect of the Securities of such series and the coupons, if any, appertaining
thereto, including the payment of the principal (and premium, if any, on) and
interest on each and all of the Securities of such series and 

<PAGE>

                                95


coupons, if any, appertaining thereto, are subordinated, to the extent and in
the manner provided in this Article Twelve, to the prior payment in full of all
Senior Indebtedness.

         This Article Twelve shall constitute a continuing offer to all persons
who, in reliance upon such provisions, become holders of, or continue to hold,
Senior Indebtedness, and such provisions are made for the benefit of the holders
of Senior Indebtedness, and such holders are made obligees hereunder and they
and/or each of them may enforce such provisions.

         SECTION 1202.  NO PAYMENT ON SECURITIES IN CERTAIN CIRCUMSTANCES.

         (a)  Upon the maturity of any Senior Indebtedness by lapse of time,
acceleration (unless waived, rescinded or annulled) or otherwise, or upon any
payment default (with or without the giving of notice or lapse of time or both,
in accordance with the terms of the instrument governing such Senior
Indebtedness, and without any waiver or forgiveness) with respect to any Senior
Indebtedness, all amounts payable thereon shall first be paid in full, or such
payment duly provided for in cash or in a manner satisfactory to the holders of
such Senior Indebtedness, before any payment is made, directly or indirectly by
set off or otherwise, on account of principal of, or interest on, the Securities
of such series or to acquire any of the Securities of such series or on account
of the redemption provisions of the Securities of such series.

         (b)  Upon a default with respect to any Senior Indebtedness (other
than under circumstances when the terms of paragraph (a) of this Section are
applicable), as such  default is defined therein or in the instrument under
which it is outstanding, permitting the holders to accelerate the maturity
thereof, upon written notice thereof given to the Company and the Trustee by the
agent or agents under the Bank Credit Agreement ("Default Notice"), then, unless
and until such default shall have been cured or waived by the holders of such
Senior Indebtedness or shall have ceased to exist, no direct or indirect payment
shall be made by the Company with respect to the principal of, or interest on,
the Securities of such series and the coupons, if any, appertaining thereto
(other than payments made in Junior Securities) or to acquire any of such
Securities or on account of the redemption provisions of the Securities of such
series and the coupons, if any, appertaining thereto; PROVIDED, HOWEVER, that
this paragraph (b) shall not prevent the making of any payment (which is not
otherwise prohibited by paragraph (a)) for more than 120 days after the Default
Notice shall have been given unless the Senior Indebtedness in respect of which
such event of default exists has been declared due and payable in its entirety,
in which case no such payment may be made until such acceleration has been
rescinded or annulled or such Senior Indebtedness has been paid in full. 
Notwithstanding the foregoing, not more than one Default Notice shall be given
with respect to Senior Indebtedness within a period of 240 consecutive days.

<PAGE>

                                96


         (c)  If, notwithstanding the foregoing provisions of this Section, any
payment on account of principal of, or interest on, the Securities of such
series or of any coupon appertaining thereto shall be received by the Trustee,
by any Holder or by any Paying Agent (or, if the Company is acting as its own
Paying Agent, money for any such payment is segregated and held in trust), then,
unless and until such payment is no longer prohibited by this Section, such
payment (subject to the provisions of Sections 1206 and 1207) shall be held in
trust for the benefit of the holders of Senior Indebtedness and, upon notice to
the Trustee or such Paying Agent from the representative of the holders of the
Senior Indebtedness and pursuant to the directions of such representative, shall
be paid over or delivered to the holders of Senior Indebtedness or their
representative(s), ratably according to the aggregate amount remaining unpaid on
account of the principal of and interest on the Senior Indebtedness held or
represented by each, for application to the payment or prepayment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all Senior
Indebtedness in full in accordance with its terms, after giving effect to any
concurrent payment or distribution or provision therefor to or for the holders
of Senior Indebtedness.  Promptly after becoming aware thereof, the Company
shall give written notice to the Trustee of any event prohibiting payments on
account of principal of, or interest on, the Securities of any series and any
coupons appertaining thereto and, in such event, shall provide to the Trustee,
in the form of an Officers' Certificate, the names and addresses of the holders
of such Senior Indebtedness and their representative(s), if any, the amount of
the Senior Indebtedness held by each such holder, any information necessary to
calculate the daily or other increase in Senior Indebtedness held by such
holders and any other information which the Trustee may reasonably request to
comply with this Article.  Subject to the provisions of Section 1203 hereof, in
the event that the Trustee or the Paying Agent reasonably determines that
additional evidence is required with respect to any person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee or the Paying Agent, as the case may be, may request that
such person furnish evidence to its reasonable satisfaction as to the amount of
Senior Indebtedness held by each such person, as to the extent such person is
entitled to participate in such payment or distribution and as to other facts
pertinent to the rights of such persons under this Article and if such evidence
is not furnished, the Trustee or the Paying Agent, as the case may be, may defer
any payment to such person pending judicial determination as to the right of
such person to receive such payment.

         SECTION 1203.  SECURITIES SUBORDINATED TO PRIOR PAYMENT OF ALL SENIOR
INDEBTEDNESS ON DISSOLUTION, WINDING-UP, LIQUIDATION OR REORGANIZATION OF THE
COMPANY.

         Upon any payment by or distribution of the assets of the Company to
creditors upon any dissolution, winding up, liquidation or reorganization of the
Company (whether in a bankruptcy or reorganization case, insolvency or
receivership proceedings, voluntary liquidation or upon any assignment for the
benefit of creditors or otherwise):

<PAGE>

                                97


         (1)  the holders of all Senior Indebtedness shall first be entitled to
    receive payment in full of all amounts payable thereon, or provision shall
    be made for such payment, before the Holders of any Security of such series
    or of any coupon appertaining thereto are entitled to receive any payment
    or distribution (other than in Junior Securities) on account of the
    principal of, or interest on, such Securities or coupons;

         (2)  any payment by, or distribution of assets of, the Company of any
    kind or character, whether in cash, property or securities (other than
    Junior Securities) to which the Holders or the Trustee on behalf of the
    Holders would be entitled except for the provisions of this Article Twelve,
    including any such payment or distribution which may be payable or
    deliverable by reason of the payment of any other Indebtedness of the
    Company being subordinated to the payment of the Securities of such series
    and the coupons appertaining thereto, if any, shall be paid by the
    liquidating trustee or agent or other Person making such a payment or
    distribution, directly to the holders of Senior Indebtedness or their
    representative(s), ratably according to the aggregate amounts remaining
    unpaid on account of the principal of and interest on the Senior
    Indebtedness held or represented by each, for application to payment of all
    Senior Indebtedness remaining unpaid, to the extent necessary to pay all
    Senior Indebtedness in full after giving effect to any concurrent payment
    or distribution, or provision therefor, to the holders of such Senior
    Indebtedness; and

         (3)  if, notwithstanding the foregoing, any payment or distribution of
    assets of the Company of any kind or character, whether in cash, property
    or securities (other than Junior Securities), shall be received by the
    Trustee or the Holders or any Paying Agent (or, if the Company is acting as
    its own Paying Agent, money for any such payment or distribution is
    segregated or held in trust) on account of principal of, or interest on,
    the Securities of such series and the coupons appertaining thereto, if any,
    before all Senior Indebtedness is paid in full, or effective provision made
    for its payment, such payment or distribution (subject to the provisions of
    Sections 1206 and 1207) shall be received and held in trust for and shall
    be paid over to the holders of the Senior Indebtedness remaining unpaid or
    unprovided for or their representative(s), ratably according to the
    aggregate amounts remaining unpaid on account of the principal of and
    interest on the Senior Indebtedness held or represented by each, for
    application to payment or prepayment of all Senior Indebtedness remaining
    unpaid, to the extent necessary to pay all Senior Indebtedness in full,
    after giving effect to any concurrent payment or distribution, or provision
    therefor, to the holders of such Senior Indebtedness.

         If the Company effects a transaction permitted by Article Eight, such
transaction shall not be deemed to be a dissolution, winding up, liquidation or
reorganization of the Company for purposes of this Section.

<PAGE>

                                98


         The Company shall give prompt written notice to the Trustee of any
dissolution, winding up, liquidation or reorganization of the Company or
assignment for the benefit of creditors by the Company.

         Upon any distribution of assets of the Company referred to in this
Article, the Trustee, subject to the provisions of Sections 601 and 602, and the
Holders of Securities of any series or of any coupon appertaining thereto shall
be entitled to rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding up or liquidation proceeding, or
bankruptcy or reorganization case, is pending, or a certificate of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to such Holders, for the purpose of ascertaining the persons entitled
to participate in such distribution, the holders of the Senior Indebtedness of
the Company and other Indebtedness of the Company, the amount thereof payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article.

         SECTION 1204.  SECURITYHOLDERS TO BE SUBROGATED TO RIGHTS OF HOLDERS
OF SENIOR INDEBTEDNESS.

         Upon payment in full of all Senior Indebtedness, the Holders of
Securities of such series or of any coupon appertaining thereto shall be
subrogated (equally and ratably with the holders of all Indebtedness of the
Company which by its terms is not superior in right of payment to the Securities
of any series or of any coupons appertaining thereto and which ranks on a parity
with the Securities of such series) to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until all amounts owing on such Securities
and coupons, if any, shall be paid in full, and for the purposes of such
subrogation no payments or distributions to the holders of Senior Indebtedness
by the Company to which the Holders would be entitled except for the provisions
of this Article, and no payment pursuant to the provisions of this Article to
the holders of Senior Indebtedness shall, as between the Company, its creditors
(other than the holders of Senior Indebtedness) and the Holders, be deemed to be
payment by the Company to or on account of the Senior Indebtedness, it being
understood that the provisions of this Article are intended solely for the
purpose of defining the relative rights of the Holders of Securities of such
series, on the one hand, and the holders of Senior Indebtedness, on the other
hand.

         If any payment or distribution to which the Holders of Securities of
any series or of any coupon appertaining thereto would otherwise have been
entitled but for the provisions of this Article shall have been applied,
pursuant to the provisions of this Article, to the payment of all amounts
payable under the Senior Indebtedness, then and in such case, the Company
specifically agrees that such Holders shall be entitled to receive from the
holders of such Senior Indebtedness at the time outstanding any payments or
distributions 

<PAGE>

                                99


received by such holders of Senior Indebtedness in excess of the amount
sufficient to pay all amounts payable under or in respect of the Senior
Indebtedness in full.

         SECTION 1205.  OBLIGATIONS OF THE COMPANY UNCONDITIONAL.

         Nothing contained in this Article Twelve or elsewhere in this
Indenture or in any Security of any series is intended to or shall impair, as
between the Company, its creditors (other than the holders of Senior
Indebtedness) and the Holders of Securities of any series and the coupons, if
any, appertaining thereto, the obligation of the Company, which is absolute and
unconditional, to pay to the Holders the principal of and interest on, the
Securities of such series and the coupons, if any, appertaining thereto, as and
when the same shall become due and payable in accordance with their terms, or to
affect the relative rights of such Holders and creditors of the Company (other
than the holders of Senior Indebtedness), nor shall anything herein or therein
prevent the Trustee or any such Holder from exercising all remedies otherwise
permitted by applicable law upon default under this Indenture, subject to the
rights, if any, under this Article of the holders of Senior Indebtedness in
respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

         SECTION 1206.  KNOWLEDGE OF TRUSTEE.

         Notwithstanding the provisions of this Article or any other provision
of this Indenture, the Trustee shall not at any time be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee, or the taking of any other action under this Indenture by the
Trustee, unless and until two Business Days after the Trustee shall have
received written notice thereof from the Company, any Holder, any Paying Agent
or any holder of Senior Indebtedness or its representative.

         SECTION 1207.  APPLICATION BY TRUSTEE OR PAYING AGENT OF ASSETS
DEPOSITED WITH IT.

         If on a date not less than two Business Days prior to the date on
which by the terms of this Indenture any monies deposited with the Trustee or
any Paying Agent (other than the Company, if it acts as Paying Agent) may become
payable for any purpose (including, without limitation, the payment of either
principal of, or interest on, any Security of any series and the coupons, if
any, appertaining thereto), the Trustee or such Paying Agent shall not have
received with respect to such payment the written notice provided for in Section
1206, then the Trustee or such Paying Agent shall have full power and authority
to receive such monies and to apply them to the purpose for which they were
received, and shall not be affected by any notice to the contrary which may be
received by it on or after such date, without, however, limiting any rights that
holders of Senior Indebtedness may 

<PAGE>

                               100


have to recover any such payments from the Holders in accordance with the
provisions of this Article.

         SECTION 1208.  SUBORDINATION RIGHTS NOT IMPAIRED BY ACTS OR OMISSIONS
OF COMPANY OR HOLDERS OF SENIOR INDEBTEDNESS.

         No right of any present or future holders of any Senior Indebtedness
to enforce the subordination herein shall at any time or in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms of this Indenture, regardless of any
knowledge thereof which any such holder may have or be otherwise charged with. 
The holders of Senior Indebtedness may extend, renew, modify, or increase Senior
Indebtedness or amend the terms of the Senior Indebtedness or any security or
guarantee therefor and release, sell or exchange such security or guarantee and
otherwise deal freely with the Company, all without affecting the liabilities
and obligations of the parties to this Indenture or the Holders.

         SECTION 1209.  SECURITYHOLDERS AUTHORIZE TRUSTEE TO EFFECTUATE
SUBORDINATION OF SECURITIES.

         Each Holder by his acceptance of the Securities of such series and the
coupons, if any, appertaining thereto, authorizes and expressly directs the
Trustee on his behalf to take such action as may be necessary or appropriate to
effectuate the subordination provided in this Article and appoints the Trustee
his attorney-in-fact for such purpose, including, in the event of any
dissolution, winding up, liquidation or reorganization of the Company (whether
in a bankruptcy or reorganization case, insolvency or receivership proceedings,
voluntary liquidation or upon an assignment for the benefit of creditors or
otherwise) tending towards liquidation of the business and assets of the
Company, the immediate filing of a claim for the unpaid balance of its or his
Securities in the form required in such proceeding and cause such claim to be
approved.  If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding on or prior to 30 days before the expiration of
the time to file such claim or claims, then the holders of the Senior
Indebtedness or their representative(s) are hereby authorized to have the right
to file and are hereby authorized to file an appropriate claim for and on behalf
of the Holders.

         SECTION 1210.  TRUSTEE NOT FIDUCIARY FOR HOLDERS OF SENIOR
INDEBTEDNESS.

         Neither the Trustee nor any Paying Agent (including the Company if the
Company acts as Paying Agent) shall be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness.  Neither the Trustee nor any Paying Agent shall
be liable to any such holder (subject to Section 1206 hereof, except for its own
gross negligence or willful misconduct) if any of them shall mistakenly pay over
or distribute to Holders of the 

<PAGE>

                               101


Securities of any series and the coupons, if any, appertaining thereto, the
Company or any other person monies or assets to which any holders of Senior
Indebtedness shall be entitled by virtue of this Article or otherwise. 
With respect to the holders of Senior Indebtedness, the Trustee or the Paying
Agent undertakes to perform or to observe only such of its covenants and
obligations as are specifically set forth in this Article, and no implied
covenants or obligations with respect to the holders of Senior Indebtedness
shall be read into this Indenture against the Trustee or the Paying Agent.

         SECTION 1211.  RIGHT OF TRUSTEE TO HOLD SENIOR INDEBTEDNESS.

         The Trustee shall be entitled to all of the rights set forth in this
Article in respect of any Senior Indebtedness at any time held by it, to the
same extent as any other holder of Senior Indebtedness, and nothing in this
Indenture shall be construed to deprive the Trustee of any of its rights as such
holder.

         SECTION 1212.  ARTICLE TWELVE NOT TO PREVENT EVENTS OF DEFAULT.

         The failure to make a payment on account of principal of or interest
on the Securities by reason of any provision of this Article shall not be
construed as preventing the occurrence of an Event of Default under Section 501.
Nothing contained in this Article Twelve shall limit the right of the Trustee or
the Holders of Securities of such series and the coupons, if any, appertaining
thereto, to take any action to accelerate the maturity of the Securities
pursuant to Section 502 or to pursue any rights or remedies hereunder; PROVIDED
that all Senior Indebtedness then or thereafter due or declared to be due shall
first be paid in full before such Holders or the Trustee are entitled to receive
any payment from the Company of principal of, or interest on, the Securities.

         SECTION 1213.  TRUSTEE'S COMPENSATION NOT PREJUDICED.

         Nothing in this Article shall apply to amounts due to the Trustee
pursuant to Section 606.


                         ARTICLE THIRTEEN

                          SINKING FUNDS

         SECTION 1301.  APPLICABILITY OF ARTICLE.

         Retirements of Securities of any series pursuant to any sinking fund
shall be made in accordance with the terms of such Securities and (except as
otherwise specified as contemplated by Section 301 for Securities of any series)
in accordance with this Article.

<PAGE>

                               102


         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1302.  Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

         SECTION 1302.  SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

         Subject to Section 1303, in lieu of making all or any part of any
mandatory sinking fund payment with respect to any Securities of a series in
cash, the Company may at its option (1) deliver to the Trustee Outstanding
Securities of a series (other than any previously called for redemption)
theretofore purchased or otherwise acquired by the Company together in the case
of any Bearer Securities of such series with all unmatured coupons appertaining
thereto, and/or (2) receive credit for the principal amount of Securities of
such series which have been previously delivered to the Trustee by the Company
or for Securities of such series which have been redeemed either at the election
of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any
mandatory sinking fund payment with respect to the Securities of the same series
required to be made pursuant to the terms of such Securities as provided for by
the terms of such series; PROVIDED, HOWEVER, that such Securities have not been
previously so credited.  Such Securities shall be received and credited for such
purpose by the Trustee at the Redemption Price specified in such Securities for
redemption through operation of the sinking fund and the amount of such
mandatory sinking fund payment shall be reduced accordingly.

         SECTION 1303.  REDEMPTION OF SECURITIES FOR SINKING FUND.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash in the Currency in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series and except, if applicable, as
provided in Sections 313(b), 313(d) and 313(e)) and the portion thereof, if any,
which is to be satisfied by delivering or crediting Securities of that series
pursuant to Section 1302 (which Securities will, if not previously delivered,
accompany such certificate) and whether the Company intends to exercise its
right to make a permitted optional sinking fund payment with respect to such
series.  Such certificate shall be irrevocable and upon its delivery the 

<PAGE>

                               103



Company shall be obligated to make the cash payment or payments therein referred
to, if any, on or before the next succeeding sinking fund payment date.  In the
case of the failure of the Company to deliver such certificate, the sinking fund
payment due on the next succeeding sinking fund payment date for that series
shall be paid entirely in cash and shall be sufficient to redeem the principal
amount of such Securities subject to a mandatory sinking fund payment without
the option to deliver or credit Securities as provided in Section 1302 and
without the right to make any optional sinking fund payment, if any, with
respect to such series.

         Not more than 60 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104.  Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

         Prior to any sinking fund payment date, the Company shall pay to the
Trustee or a Paying Agent (or, if the Company is acting as its own Paying Agent,
segregate and hold in trust as provided in Section 1003) in cash a sum equal to
any interest that will accrue to the date fixed for redemption of Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 1303.

         Notwithstanding the foregoing, with respect to a sinking fund for any
series of Securities, if at any time the amount of cash to be paid into such
sinking fund on the next succeeding sinking fund payment date, together with any
unused balance of any preceding sinking fund payment or payments for such
series, does not exceed in the aggregate $100,000, the Trustee, unless requested
by the Company, shall not give the next succeeding notice of the redemption of
Securities of such series through the operation of the sinking fund.  Any such
unused balance of moneys deposited in such sinking fund shall be added to the
sinking fund payment for such series to be made in cash on the next succeeding
sinking fund payment date or, at the written request of the Company, shall be
applied at any time or from time to time to the purchase of Securities of such
series, by public or private purchase, in the open market or otherwise, at a
purchase price for such Securities (excluding accrued interest and brokerage
commissions, for which the Trustee or any Paying Agent will be promptly
reimbursed by the Company) not in excess of the principal amount thereof.

                         ARTICLE FOURTEEN

                  REPAYMENT AT OPTION OF HOLDERS

         SECTION 1401.  APPLICABILITY OF ARTICLE.

         Repayment of Securities of any series before their Stated Maturity at
the option of Holders thereof shall be made in accordance with the terms of such
Securities and (except as otherwise specified as contemplated by Section 301 for
Securities of any series) in accordance with this Article.

         SECTION 1402.  REPAYMENT OF SECURITIES.

         Securities of any series subject to repayment in whole or in part at
the option of the Holders thereof will, unless otherwise provided in the terms
of such Securities, be repaid at a price equal to the principal amount thereof,
together with interest, if any, thereon accrued to the Repayment Date specified
in or pursuant to the terms of such Securities.  The Company covenants that on
or before the Repayment Date it will deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money in the Currency in
which the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series and except, if
applicable, as provided in Sections 313(b), 313(d) and 313(e)) sufficient to pay
the principal (or, if so provided by the terms of the Securities of any series,
a percentage of the principal) of and (except if the Repayment Date shall be an
Interest Payment Date) accrued interest, if any, on, all the Securities or
portions thereof, as the case may be, to be repaid on such date.

         SECTION 1403.  EXERCISE OF OPTION.

         Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on the reverse
of such Securities.  To be repaid at the option of the Holder, any Security so
providing for such repayment, with the "Option to Elect Repayment" form on the
reverse of such Security duly completed by the Holder (or by the Holder's
attorney duly authorized in writing), must be received by the Company at the
Place of Payment therefor specified in the terms of such Security (or at such
other place or places of which the Company shall from time to time notify the
Holders of such Securities) not earlier than 45 days nor later than 30 days
prior to the Repayment Date.  If less than the entire principal amount of such
Security is to be repaid in accordance with the terms of such Security, the
principal amount of such Security to be repaid, in increments of the minimum
denomination for Securities of such series, and the denomination or
denominations of the Security or Securities to be issued to the Holder for the
portion of the principal amount of such Security surrendered that is not to be
repaid, must be specified.  

<PAGE>

                               105


The principal amount of any Security providing for repayment at the option of
the Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of the series of which such Security to be
repaid is a part.  Except as otherwise may be provided by the terms of any
Security providing for repayment at the option of the Holder thereof, exercise
of the repayment option by the Holder shall be irrevocable unless waived by the
Company.

         SECTION 1404.  WHEN SECURITIES PRESENTED FOR REPAYMENT BECOME DUE AND
PAYABLE.

         If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void.  Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
PROVIDED, HOWEVER, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and PROVIDED FURTHER that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable to the Holders of such Securities,
or one or more Predecessor Securities, registered as such at the close of
business on the relevant Record Dates according to their terms and the
provisions of Section 308.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1402 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; PROVIDED, HOWEVER, that interest represented
by coupons shall be payable only at an 

<PAGE>

                               106


office or agency located outside the United States (except as otherwise provided
in Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.

         If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

         SECTION 1405.  SECURITIES REPAID IN PART.

         Upon surrender of any Registered Security which is to be repaid in
part only, the Company shall execute and the Trustee shall authenticate and
deliver to the Holder of such Security, without service charge and at the
expense of the Company, a new Registered Security or Securities of the same
series, of any authorized denomination specified by the Holder, in an aggregate
principal amount equal to and in exchange for the portion of the principal of
such Security so surrendered which is not to be repaid.


                         ARTICLE FIFTEEN

                DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1501.  COMPANY'S OPTION TO EFFECT DEFEASANCE OR COVENANT
DEFEASANCE.

         Except as otherwise specified as contemplated by Section 301 for
Securities of any series, the provisions of this Article Fifteen shall apply to
each series of Securities, and the Company may, at its option, effect defeasance
of the Securities of or within a series under Section 1502, or covenant
defeasance of or within a series under Section 1503 in accordance with the terms
of such Securities and in accordance with this Article.

         SECTION 1502.  DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations with respect to such
Outstanding Securities and any related coupons on the date the conditions set
forth in Section 1504 are satisfied (hereinafter, "defeasance").  For this
purpose, such defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by such Outstanding Securities
and any related coupons, which shall thereafter be deemed to be "Outstanding" 

<PAGE>

                               107


only for the purposes of Section 1505 and the other Sections of this Indenture
referred to in (A) and (B) below, and to have satisfied all its other
obligations under such Securities and any related coupons and this Indenture
insofar as such Securities and any related coupons are concerned (and the
Trustee, at the expense of the Company, shall execute proper instruments
acknowledging the same), except for the following which shall survive until
otherwise terminated or discharged hereunder:  (A) the rights of Holders of such
Outstanding Securities and any related coupons to receive, solely from the trust
fund described in Section 1504 and as more fully set forth in such Section,
payments in respect of the principal of (and premium, if any) and interest, if
any, on such Securities and any related coupons when such payments are due,
(B) the Company's obligations with respect to such Securities under Sections
304, 305, 306, 1002 and 1003, (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (D) this Article Fifteen.  Subject to
compliance with this Article Fifteen, the Company may exercise its option under
this Section 1502 notwithstanding the prior exercise of its option under
Section 1503 with respect to such Securities and any related coupons.

         SECTION 1503.  COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 1502 of the option
applicable to this Section 1503 with respect to any Securities of or within a
series, the Company shall be released from its obligations under any covenant
under Article Eight and in Sections 1004 through 1012, and, if specified
pursuant to Section 301, its obligations under any other covenant, with respect
to such Outstanding Securities and any related coupons on and after the date the
conditions set forth in Section 1504 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any related coupons shall thereafter be
deemed to be not "Outstanding" for the purposes of any direction, waiver,
consent or declaration or Act of Holders (and the consequences of any thereof)
in connection with such covenants, but shall continue to be deemed "Outstanding"
for all other purposes hereunder (it being understood that such Securities shall
not be deemed Outstanding for financial accounting purposes).  For this purpose,
such covenant defeasance means that, with respect to such Outstanding Securities
and any related coupons, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of reference in any such covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Section 501(4) or
Section 501(9) or otherwise, as the case may be, but, except as specified above,
the remainder of this Indenture and such Securities and any related coupons
shall be unaffected thereby.  In addition, upon the Company's exercise under
Section 1501 of the option applicable to Section 1503, Sections 501(4) through
(6) shall not constitute Events of Default.

<PAGE>

                               108


         SECTION 1504.  CONDITIONS TO DEFEASANCE OR COVENANT DEFEASANCE.

         The following shall be the conditions to application of either
Section 1502 or Section 1503 to any Outstanding Securities of or within a series
and any related coupons:

         (1)  The Company shall irrevocably have deposited or caused to be
    deposited with the Trustee (or another trustee satisfying the requirements
    of Section 607 who shall agree to comply with the provisions of this
    Article Fifteen applicable to it) as trust funds in trust for the purpose
    of making the following payments, specifically pledged as security for, and
    dedicated solely to, the benefit of the Holders of such Securities and any
    related coupons, (A) an amount (in such Currency in which such Securities
    and any related coupons are then specified as payable at Stated Maturity),
    or (B) Government Obligations applicable to such Securities (determined on
    the basis of the Currency in which such Securities are then specified as
    payable at Stated Maturity) which through the scheduled payment of
    principal and interest in respect thereof in accordance with their terms
    will provide, not later than one day before the due date of any payment of
    principal of and premium, if any, and interest, if any, under such
    Securities and any related coupons, money in an amount, or (C) a
    combination thereof, sufficient, in the opinion of a nationally recognized
    firm of independent public accountants expressed in a written certification
    thereof delivered to the Trustee, to pay and discharge, and which shall be
    applied by the Trustee (or other qualifying trustee) to pay and discharge,
    (i) the principal of (and premium, if any) and interest, if any, on such
    Outstanding Securities and any related coupons on the Stated Maturity (or
    Redemption Date, if applicable) of such principal (and premium, if any) or
    installment of interest, if any, and (ii) any mandatory sinking fund
    payments or analogous payments applicable to such Outstanding Securities
    and any related coupons on the day on which such payments are due and
    payable in accordance with the terms of this Indenture and of such
    Securities and any related coupons; PROVIDED that the Trustee shall have
    been irrevocably instructed to apply such money or the proceeds of such
    Government Obligations to said payments with respect to such Securities and
    any related coupons.  Before such a deposit, the Company may give to the
    Trustee, in accordance with Section 1102 hereof, a notice of its election
    to redeem all or any portion of such Outstanding Securities at a future
    date in accordance with the terms of the Securities of such series and
    Article Eleven hereof, which notice shall be irrevocable.  Such irrevocable
    redemption notice, if given, shall be given effect in applying the
    foregoing.

         (2)  No Default or Event of Default with respect to such Securities or
    any related coupons shall have occurred and be continuing on the date of
    such deposit or, insofar as paragraphs (7) and (8) of Section 501 are
    concerned, at any time during the 

<PAGE>

                               109


    period ending on the 91st day after the date of such deposit (it being
    understood that this condition shall not be deemed satisfied until the
    expiration of such period).


         (3)  No event or condition shall exist that, pursuant to the
    provisions of Section 1202 or 1203, would prevent the Company from making
    payments of the principal of (and premium, if any) or interest on the
    Securities on the date of such deposit or at any time during the period
    ending on the 91st day after the date of such deposit (it being understood
    that this condition shall not be deemed satisfied until the expiration of
    such period).

         (4)  Such defeasance or covenant defeasance shall not result in a
    breach or violation of, or constitute a default under, this Indenture or
    any other material agreement or instrument to which the Company is a party
    or by which it is bound.

         (5)  In the case of an election under Section 1502, the Company shall
    have delivered to the Trustee an Opinion of Counsel stating that (x) the
    Company has received from, or there has been published by, the Internal
    Revenue Service a ruling, or (y) since the date of execution of this
    Indenture, there has been a change in the applicable federal income tax
    law, in either case to the effect that, and based thereon such opinion
    shall confirm that, the Holders of such Outstanding Securities and any
    related coupons will not recognize income, gain or loss for federal income
    tax purposes as a result of such defeasance and will be subject to federal
    income tax on the same amounts, in the same manner and at the same times as
    would have been the case if such defeasance had not occurred.

         (6)  In the case of an election under Section 1503, the Company shall
    have delivered to the Trustee an Opinion of Counsel to the effect that the
    Holders of such Outstanding Securities and any related coupons will not
    recognize income, gain or loss for federal income tax purposes as a result
    of such covenant defeasance and will be subject to federal income tax on
    the same amounts, in the same manner and at the same times as would have
    been the case if such covenant defeasance had not occurred.

         (7)  In the case of an election under either Section 1502 or 1503, the
    Company shall represent to the Trustee that the deposit made by the Company
    pursuant to its election under Section 1502 or 1503 was not made by the
    Company with the intent of preferring the Holders of Securities of any
    series over other creditors of the Company or with the intent of defeating,
    hindering, delaying or defrauding creditors of the Company or others.

         (8)  Notwithstanding any other provisions of this Section, such
    defeasance or covenant defeasance shall be effected in compliance with any
    additional or 

<PAGE>

                               110


    substitute terms, conditions or limitations in connection therewith
    pursuant to Section 301.

         (9)  The Company shall have delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that all conditions
    precedent provided for relating to either the defeasance under Section 1502
    or the covenant defeasance under Section 1503 (as the case may be) have
    been complied with.

         SECTION 1505.  DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST; OTHER MISCELLANEOUS PROVISIONS.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations (or other property as may be provided pursuant
to Section 301) (including the proceeds thereof) deposited with the Trustee (or
other qualifying trustee, collectively for purposes of this Section 1505, the
"Trustee") pursuant to Section 1504 in respect of such Outstanding Securities
and any related coupons shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any related coupons and
this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities and any related coupons of all sums
due and to become due thereon in respect of principal (and premium, if any) and
interest, if any, but such money need not be segregated from other funds except
to the extent required by law.  Money and U.S. Government Obligations so held in
trust are not subject to Article Twelve.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1504(1) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 313(b) or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 1504(1) has been made in respect of such Security, or (b) a
Conversion Event occurs as contemplated in Section 313(d) or 313(e) or by the
terms of any Security in respect of which the deposit pursuant to
Section 1504(1) has been made, the indebtedness represented by such Security and
any related coupons shall be deemed to have been, and will be, fully discharged
and satisfied through the payment of the principal of (and premium, if any) and
interest, if any, on such Security as they become due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security becomes payable as a result of
such election or Conversion Event based on the applicable Market Exchange Rate
for such Currency in effect on the third Business Day prior to each payment
date, except, with respect to a Conversion Event, for such Currency in effect
(as nearly as feasible) at the time of the Conversion Event.

<PAGE>

                               111


         The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1504 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any related
coupons.

         Anything in this Article Fifteen to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in Section 1504 which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent defeasance or covenant defeasance, as applicable, in accordance with
this Article.

         SECTION 1506.  REINSTATEMENT.

         If the Trustee or any Paying Agent is unable to apply any money in
accordance with Section 1505 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and such
Securities and any related coupons shall be revived and reinstated as though no
deposit had occurred pursuant to Section 1502 or 1503, as the case may be, until
such time as the Trustee or Paying Agent is permitted to apply all such money in
accordance with Section 1505; PROVIDED, HOWEVER, that if the Company makes any
payment of principal of (or premium, if any) or interest, if any, on any such
Security or any related coupon following the reinstatement of its obligations,
the Company shall be subrogated to the rights of the Holders of such Securities
and any related coupons to receive such payment from the money held by the
Trustee or Paying Agent.


                         ARTICLE SIXTEEN

                MEETINGS OF HOLDERS OF SECURITIES

         SECTION 1601.  PURPOSES FOR WHICH MEETINGS MAY BE CALLED.

         If Securities of a series are issuable as Bearer Securities, a meeting
of Holders of Securities of such series may be called at any time and from time
to time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such

         SECTION 1602.  CALL, NOTICE AND PLACE OF MEETINGS.

         (a)  The Trustee may at any time call a meeting of Holders of
Securities of any series for any purpose specified in Section 1601, to be held
at such time and at such place in The City of New York or in London as the
Trustee shall determine.  Notice of every meeting of Holders of Securities of
any series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided for in Section 106, not less than 21 nor more than 180 days
prior to the date fixed for the meeting.

         (b)  In case at any time the Company, pursuant to a Board Resolution,
or the Holders of at least 10% in principal amount of the Outstanding Securities
of any series shall have requested the Trustee to call a meeting of the Holders
of Securities of such series for any purpose specified in Section 1601, by
written request setting forth in reasonable detail the action proposed to be
taken at the meeting, and the Trustee shall not have made the first publication
of the notice of such meeting within 21 days after receipt of such request or
shall not thereafter proceed to cause the meeting to be held as provided herein,
then the Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place in The City
of New York or in London for such meeting and may call such meeting for such
purposes by giving notice thereof as provided in paragraph (a) of this Section.

         SECTION 1603.  PERSONS ENTITLED TO VOTE AT MEETINGS.

         To be entitled to vote at any meeting of Holders of Securities of any
series, a Person shall be (1) a Holder of one or more Outstanding Securities of
such series, or (2) a Person appointed by an instrument in writing as proxy for
a Holder or Holders of one or more Outstanding Securities of such series by such
Holder or Holders.  The only Persons who shall be entitled to be present or to
speak at any meeting of Holders of Securities of any series shall be the Person
entitled to vote at such meeting and their counsel, any representatives of the
Trustee and its counsel and any representatives of the Company and its counsel.

         SECTION 1604.  QUORUM; ACTION.

         The Persons entitled to vote a majority in principal amount of the
Outstanding Securities of a series shall constitute a quorum for a meeting of
Holders of Securities of such series; PROVIDED, HOWEVER, that, if any action is
to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of not less than a
specified percentage in principal amount of the Outstanding Securities of a
series, the Persons entitled to vote such specified percentage in principal
amount of the Outstanding Securities of such series shall constitute a quorum. 
In the absence of a quorum 

<PAGE>

                               113


within 30 minutes of the time appointed for any such meeting, the meeting shall,
if convened at the request of Holders of Securities of such series, be
dissolved.  In any other case the meeting may be adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such meeting.  In the absence of a quorum at any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not
less than 10 days as determined by the chairman of the meeting prior to the
adjournment of such adjourned meeting.  Notice of the reconvening of any
adjourned meeting shall be given as provided in Section 1602(a), except that
such notice need be given only once not less than five days prior to the date on
which the meeting is scheduled to be reconvened.  Notice of the reconvening of
any adjourned meeting shall state expressly the percentage, as provided above,
of the principal amount of the Outstanding Securities of such series which shall
constitute a quorum.

         Subject to the foregoing, at the reconvening of any meeting adjourned
for lack of a quorum the Persons entitled to vote 25% in principal amount of the
Outstanding Securities at the time shall constitute a quorum for the taking of
any action set forth in the notice of the original meeting.

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the Holders of
not less than a majority in principal amount of the Outstanding Securities of
such series; PROVIDED, HOWEVER, that, except as limited by the proviso to
Section 902, any resolution with respect to any request, demand, authorization,
direction, notice, consent, waiver or other action which this Indenture
expressly provides may be made, given or taken by the Holders of a specified
percentage, which is less than a majority, in principal amount of the
Outstanding Securities of a series may be adopted at a meeting or an adjourned
meeting duly reconvened and at which a quorum is present as aforesaid by the
affirmative vote of the Holders of not less than such specified percentage in
principal amount of the Outstanding Securities of such series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

         Notwithstanding the foregoing provisions of this Section 1604, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

<PAGE>

                               114


         (i)  there shall be no minimum quorum requirement for such meeting;
    and

         (ii) the principal amount of the Outstanding Securities of such series
    that vote in favor of such request, demand, authorization, direction,
    notice, consent, waiver or other action shall be taken into account in
    determining whether such request, demand, authorization, direction, notice,
    consent, waiver or other action has been made, given or taken under this
    Indenture.

         SECTION 1605.  DETERMINATION OF VOTING RIGHTS; CONDUCT AND ADJOURNMENT
OF MEETINGS.

         (a)  Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate. 
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities.  Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

         (b)  The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1602(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman.  A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c)  At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of Outstanding
Securities of such series held or represented by him (determined as specified in
the definition of "Outstanding" in Section 101); PROVIDED, HOWEVER, that no vote
shall be cast or counted at any meeting in respect of any Security challenged as
not Outstanding and ruled by the chairman of the meeting to be not Outstanding. 
The chairman of the meeting shall have no right to vote, except as a Holder of a
Security of such series or proxy.

<PAGE>

                               115


         (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 1602 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting; and the
meeting may be held as so adjourned without further notice.

         SECTION 1606.  COUNTING VOTES AND RECORDING ACTION OF MEETINGS.

         The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the Secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1602 and, if
applicable, Section 1604.  Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting.  Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

         This Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
shall together constitute but one and the same Indenture.

         This is to certify that as of the date hereof, and except as set forth
below, the above-captioned Securities held by you for our account (i) are owned

partnerships, domestic corporations or any estate or trust the income of which
is subject to United States federal income taxation regardless of its source

(a) foreign branches of United States financial institutions (financial
institutions, as defined in United States Treasury Regulations
Section 2.165-12(c)(1)(v) are herein referred to as "financial institutions")
purchasing for their own account or for resale, or (b) United States person(s)
who acquired the Securities through foreign branches of United States financial
institutions and who hold the Securities through such United States financial
institutions on the date hereof (and in either case (a) or (b), each such United
States financial institution hereby agrees, on its own behalf or through its
agent, that you may advise Cablevision Systems Corporation or its agent that
such financial institution will comply with the requirements of
Section 165(j)(3)(A), (B) or (C) of the United States Internal Revenue Code of

Cablevision Systems Corporation,
   One Media Crossways,
      Woodbury, New York 11797

Dear Sirs:

         In connection with the registration under the Securities Act of 1933
(the "Act") of $1,000,000,000 aggregate public offering price of debt securities
(the "Securities") of Cablevision Systems Corporation, a Delaware corporation
(the "Company"), we, as your counsel, have examined such corporate records,
certificates and other documents, and such questions of law, as we have
considered necessary or appropriate for the purposes of this opinion.


 
         Upon the basis of such examination, we advise you that, in our 
opinion, when the registration statement relating to the Securities (the 
"Registration Statement") has become effective under the Act, the applicable 
Indenture relating to the Securities has been duly authorized, executed and 
delivered, the terms of the Securities and of their issuance and sale have 
been duly established in
 

<PAGE>

Cablevision Systems Corporation                                              2

conformity with the applicable Indenture so as not to violate any
applicable law or result in a default under or breach of any agreement or
instrument binding upon the Company and so as to comply with any requirement or
restriction imposed by any court or governmental body having jurisdiction over
the Company, and the Securities have been duly executed and authenticated in
accordance with the applicable Indenture and issued and sold as contemplated in
the Registration Statement, the Securities will constitute valid and legally
binding obligations of the Company, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general equity
principles.

 
         In rendering the foregoing opinion, we are expressing no opinion
as to Federal or state laws relating to fraudulent transfers.
 

         We note that, as of the date of this opinion, a judgment for money in
an action based on a Security denominated in a foreign currency or currency unit
in a Federal or state court in the United States ordinarily would be enforced in
the United States only in United States dollars.  The date used to determine the
rate of conversion of the foreign currency unit in which a particular Security

<PAGE>

Cablevision Systems Corporation                                              3

is denominated into United States dollars will depend upon various factors,
including which court renders the judgment.  In the case of a Security
denominated in a foreign currency, a state court in the State of New York
rendering a judgment on such Security would be required under Section 27 of the
New York Judiciary Law to render such judgment in the foreign currency in which
the Security is denominated, and such judgment would be converted into United
States dollars at the exchange rate prevailing on the date of entry of the
judgment.

         The foregoing opinion is limited to the Federal laws of the United
States, the laws of the State of New York and the General Corporation Law of the
State of Delaware, and we are expressing no opinion as to the effect of the laws
of any other jurisdiction.

         We have relied as to certain matters on information obtained from
public officials, officers of the Company and other sources believed by us to be
responsible.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to us under the heading "Validity
of Securities" in the Prospectus.  In giving such consent, we do not 

<PAGE>

Cablevision Systems Corporation                                              4

thereby admit that we are in the category of persons whose consent is 
required under Section 7 of the Act.


                                  Very truly yours,
